My cube is highly creature based now. Without the power included or combo supported there has been a noticeable drift away from planeswalkers and spells that don't affect the board. This is due to the power creep we have seen in creatures relative to other types of card in the game over recent years. A couple of years ago it was all about planeswalkers (in my cube), they were the dominant force in the game. Get one down early enough that it isn't threatened by opposing dorks or just deploying one on a stalemate board situation and you were miles ahead as a result. Now it seems as if many dorks can handle a planeswalker fairly comfortably. Either walkers are too slow or they are too vulnerable a far higher proportion of the time. I would happily run six planeswalkers in most of my cube decks a couple of years ago, now I rarely see three or more in a deck. The average is likely below two per deck. Walkers typically are poor with 1 activation, OK with 2, and then quickly become amazing there after. Simply put, the power and tempo of creatures has reduced the life span of walkers and thus average activations which in turn reducers their expected value. Spot removal rarely bothered planeswalkers as it always meant a 1 for 1 trade but the walker player got an activation as well typically leaving them either cards or tempo up. When creatures kill the walkers they are often doing so just at the cost of an attack, and only when going face isn't better. Creatures give the attacker options and value against walkers and they now come with added power. The risk of just getting your planewalker instantly gibbed with a Questing Beast or a Fury is great and well worth avoiding. More high quality manlands has also helped to end the reign of planeswalkers as they are so hard to deal with purely at sorcery speed.
With walkers being so strong it used to be the case that Wraths and planeswalkers was a top tier strategy. These days that isn't getting it done. Either you or your walkers die before you can get off a good Wrath. A deck without (many) dorks is typically just hurting itself by not playing some of the most powerful cards on offer. Wraths are still fantastic but they are harder to use. Invariably you are killing a thing or two of your own. You either needed to deploy some things to disguise your mass removal plan and force a relevant over extension, or to simply avoid being overrun. All this leads to the title - partial and one-sided Wraths. These are quickly becoming some of the highest pick cards in my cube and are packing some of the most impressive results too. Partial and one sided Wrath effects let you play your high power dorks while still keeping your opponent in check in regards how they may go about deploying their dorks. At present mass removal that you can use effectively along side your own creatures make up a significant part of the list of best cards in cube.
A one sided Wrath is fairly straight forward, it is something that only hits their creatures such as the classic Plague Wind. A partial Wrath can be two things, the first is one that only hits certain kinds of creature, be it based on mana cost, size, or some other aspect. These in turn come in two groups; those that you can some control over the effect (such as Extinction Event) and those that are fixed (such as the basic Infest). There are also modal mass removal spells which I will put in this variable partial wrath group as they function fairly similarly in terms of picking and deck construction. Modal mass removal cards would include the likes of Sweltering Suns which offers no control over the function of the mass removal but the addition of cycling allows it to avoid being a dead card. The second type of partial Wrath is much more like a spot removal spell that hits multiple targets such as an Arc Trail or a Finale of Eternity. We shall call these removal spells limited mass removal as they are unable to kill an endless number of dorks while the others all potentially can. All these various types of one sided and partial mass removal cards allow you to play your creatures with a lot more comfort and safety than conventional Wraths while still forcing your opponent to avoid over extending else they walk into a devastating blow out on both cards and tempo.
I am going to cover and rate the various options on offer for cube for these partial and one sided mass removal cards. All of them are cube worthy to some degree or other. There are also many more that I am not going to cover as they are rather less powerful or typically too narrow. Hopefully this discussion of the best will help to allow for good appraisal of new or uncovered cards.
One Sided
Ruinous Ultimatum 4/10
Incredibly powerful but sadly too narrow and too late. You can happily play and cast 7 drops in cube if they are as game winning as this. Sadly the colours and intensity of them make this far too narrow for cube when it is competing with the likes of Ugin for space in decks. This is easily there on power level but it falls short on playability. You would get more mileage from All is Dust in a cube despite it being substantially less potent than the Ultimatum.
Mizzium Mortars 7/10
This is a fine and rounded red removal tool. It is a rare example of a card that has improved with time. It kills all but the top end things in a very dull sorcery speed one for one way. It gives good early game play and then scales up into a relatively hard hitting one sided removal spell. Great in midrange and control decks and still fine in the more aggressive ones. The kinds of decks you want mass removal against are the ones that clog up the board with smaller dorks and tokens. This means the limited nature of the 4 damage is rarely an issue. Mortars winds up in several categories being a fixed mass removal tool as well as a modal one of sorts. Both the one sided and modal natures of it are big perks, the modal arguably is the better as you wouldn't play Mortars as a 6 drop in your cube. It is cast substantially more as a 2 mana spell. Even so, the one sided aspect of the mass removal is more notable as there are relatively few playable cards in this group. This just has a pretty reasonable floor able to be an early play that is often tempo positive while having an absolutely nutty ceiling capable of just winning games. With a floor so reasonable you do not need to win many games with the other mode at all before you have a great card and this overloads to win games more than just occasionally.
Winds of Abandon 8.5/10
This is very much a riff on Mizzium Mortars and given the white treatment. This makes it far better at killing top tier threats and less ideal at killing off smaller things. Consequently this is used a whole lot more in the overload mode than Mortars, and in all kinds of deck from aggro all the way to control. White aggro decks have a tendency to either win or stall out the board. In those cases Winds is often a win on the spot. Giving away land is not a massive problem by the time you are overloading this while doing so in the early stages of the game is a bit uncomfortable and has to really need doing. On the flip side, you tend to want to save your unconditional exile quality removal for the nastiest things rather than having to "waste" it on something in the early game. Despite my knocking of this early game usage for Winds it makes the card great. Six mana one sided unconditional Wrath or two mana unconditional spot removal? Sign me all the way up. The added security and reliability this brings over Mortars more than makes up for the drawback of giving away lands. A six mana one sided Wrath is pretty strong by itself, adding a pretty playable two mana mode turns this from decent to really great and it manages to do so without feeling too oppressive or over powered. A slow mode and a fair mode keep this well in check.
Cyclonic Rift 6/10
The last in this cycle of overload tools, and these days the weakest despite having been quite a lot better than Mortars for most of their lives. Rift has the lowest impact normal mode and the highest cost overload mode. It is also a tempo play rather than a true removal spell. It used to dominate so hard thanks to planewalkers being so powerful and games being slower and more stalled out affairs. You used to beat control decks by extending with walkers and Cyclonic Rift would undo that nicely. As that strategy has waned in effectiveness and getting to 7 mana with blue has become harder Rift has moved towards the fringes of my cube. I find I want to play an Ugin or a Brazen Borrower and never the Rift anymore.
Settle the Wreckage 7.5/10
This is a card that varies a fair amount in power based on how much information your opponent has. If they are oblivious to it then you have yourself a 4 mana instant speed, exile quality, one sided Wrath. Walking into a Settle is usually game over. What keeps the card fair is knowing about it, either in the format, in their deck, or in their hand. Depending on how far ahead you are you can turn Settle into a fairly poor removal spell that is unlikely to gain value or significant tempo. This dance of working out your odds on facing a Settle and how much you can afford to play around the potential of one makes it an interesting card as well as a good one. I don't tend to play it in aggressive decks but I know players that do. I will however play it all day long in control and midrange decks. Mass removal that can hit manlands are such a delight. Settle is most akin to Wing Shard but performs its role rather better needing no support at all to take out multiple dorks.
Partial (fixed)
This group has some of the highest numbers of cards printed for it such as Infest and Pyroclasm however these tend to be too narrow to get enough play in cube. Either you want things that reliably kill everything or you want some degree of option on your card. Languish, Anger the Gods, and Pyroclasm have been the three most commonly found cards in this group in my cube over the years but they invariably get cut fairly quickly for insufficient action. I would certainly play more fixed partial mass removal spell in cube but it would have to be incredibly mana efficient to be competitive and this likely means it could only see print in something like MH or a commander product.
Pyroclasm 6/10
Pyroclasm is certainly the card that has done most work in cube and is the closest from this class of mass removal spells to getting back into the cube. It is effectively just a more polar, more swingy, and more situational Arc Trail, which itself is a powerful card in cube that already suffers from all those issues. As such I suspect that while many more well pushed fixed partial mass removal spells could be powerful and playable enough for cube I am not sure we want that as it wouldn't so likely lead to good play experiences on the whole and will also just shift the meta to the point where such cards no longer suited. As things tend towards massing smaller tokens Pyroclasm comes along and gets a few months of play and turns that trend around quickly! It is one of those limit setting cards that keeps a meta undulating back and forth. It is powerful and can be too powerful. It is so cheap and efficient relative to basically all other mass removal spells that is scales rapidly by contrast meaning that as soon as it is playable in a meta it is oppressive in that meta in turn forcing a quick shift in said meta.
Storm's Wrath 7/10
I am not entirely sure why this has done so well in cube. The card is very fair and resides at the lower end of my cubes power range. I think there are several factors at play as to why this has succeeded where other fixed output mass removal spells have failed. Firstly Storm's Wrath came at a point where red control decks were starting to become a proper high tier archetype. A good solid mass removal spell in the right range either worked nicely in the meta or just sat in a good spot for people to appreciate how the card would perform and function in contrast to Wrath of God and saw play as a result of understanding and familiarity?! Very few creatures in my cube have more than 4 toughness (18 currently which is less than 8% of dorks) and basically all of those cost five or more mana meaning that on curve, even when on the draw Storm's Wrath will be a full clear. The higher damage output makes Storm's Wrath far less situational than many other more traditional damage-each-creature red mass removal spell. Lastly, it hits walkers which was a very big deal and while it is becoming less so it is certainly still relevant. It is simply really hard to play around a Wrath that hits the two main threat types, you just have to walk into it or concede tempo by doing nothing a lot of the time. Traditionally players would "over extend" using planeswalkers as it was by far and away the safest way to push an advantage. If you ever get more than one walker killed with a Storm's Wrath you will know quite how swingy and devastating that feels. Even just having a walker, a good dork and perhaps some tokens killed with it feels like game over.
Plague Engineer 8.5/10
This card is just a dirty little spell that seems to win a lot of games. It is mostly killing tokens, thopters, goblins, that sort of thing. Sometimes it ends the career of a white or green deck with a human, elf, or even druid named. When you take out a couple of real cards early in the game, even if they are just Elite Vanguard and Llanowar Elves, with a three drop that sits in play it is devastating. You are up tempo and cards and further to that you have a relevant thing in play that is either trading up or simply sitting there stopping further deployment of certain cards and effects. Even just shrinking some guys can be a real pain. As far as mass removal effects go in cube this is pretty tame however as a card overall it is brutal. It takes the sting out of a lot of high tempo openers, offers some large blowout potential, answers annoying cards like Mother of Runes and Retrofitter Foundry, and does all of this while being a low cost to include and low risk to use. This is both more powerful than, and a lot more playable than Goblin Chainwhirler which is itself pretty powerful and not infrequently ruinous.
Extinction Event 8.5/10
This is a lot like the black Settle the Wreckage in that opponents are wise to play around it somewhat as it can be game over if walked into blindly. It is better than Settle because it neither gives away a lot of lands nor is it something you can fully play around. Extinction Event can always deal with your best dork. All you can do is try and stop it taking out too many of your dorks, or at least relative to the opponents. Fairly reliable spot removal that dabbles in outright winning the game. Mostly what this does is keep people honest. Just by existing cards like this will stop people just going all in if they don't have to which in turn leads to more longer and interactive games.
Toxic Deluge 9/10
Hard not to call this the best Wrath. It is three mana, easily splashed, and can kill everything, including the indestructible things out there. Yes, it costs some life to use but more often than not the low three mana cost of this card winds up saving more life for you than you spend on playing it. While this is generally the best mass removal spell in cube it is not the best one sided mass removal spell in that it is only one sided when you have the toughest dork in play, which is rarely. Equally, it is selective, but baring the case where you have the biggest dorks, you are only not killing everything because the life cost is too steep. Regardless, when a Wrath is this efficient you really do not need it to be all that one sided to be nuts!
Massacre Girl 8/10
Massacre Wurm 6.5/10
These are one sided in that at the very least you will have either the Girl or the Wurm still in play. Every now and again you will have something else fat but this is rare and not all that important for the strength of these cards. Girl is better as she is cheaper, less colour intense, and able to kill bigger threats. She can need a little bit of setting up but in a format like cube where chaffy tokens build up quickly she is typically a full clear without any work. Wurm on the other hand is much more of an anti weenie card being fairly little use against meaty dorks but being utterly devastating against little ones. Indeed, it often beats big dorks simply by dealing critical damage handling all the small ones that built up to it or came with it. Sure, the Avenger of Zendikar is still in play but there are a pile of dead plants and elves that means the game has swung wildly if not ended outright.
Fiery Confluence 7.5/10
A low power mass removal spell but one with versatility and flexibility. You can six people to the face meaning this is never dead and often feared on multiple fronts. This winds up in a whole lot of decks and commonly wipes the board fully or partially and leaves the caster in far better stead than they were before. This is done in aggro, midrange, and control decks alike. Just because you are playing this to hit people for six does not mean that a mass removal spell isn't what the doctor ordered now and again. One of those cards that is just versatile enough to happily be played anywhere.
Ugin, the Spirit Dragon 8/10
One of the most potent I win buttons in cube and much of the time what a control deck will aim at surviving to resolve. Ugin deals with most things and stabilizes a board pretty consistently while then also going on to be a game winning threat. Ugin deals with planeswalker and creatures and this makes him especially hard to play around, the counter play to Ugin is getting the job done before he arrives. I would have put this as a 9/10 as recently as last year but two things are nibbling away at the power of this titan. Firstly things are speeding up resulting in games ending or getting critical before Ugin is more than a dead card. Secondly, we got a pile of great new manlands which are the bane of Ugin. Either he dies on the swing back to them or worse still, you do. The highly increased frequency of seeing manlands rather reduces the security he used to bring.
Pernicious Deed 4/10
Of old this was premium board control but it has fallen by the wayside over the years for several reasons. Not answering planeswalkers was the first big blow for Deed. The second blow was more gradual but certainly much more problematic. It is simply how mana inefficient Deed is as removal. You are always X+3 mana to kill something meaning you need to kill something else of mana value three or more in addition just to stay even on tempo. It was increasingly hard to come out ahead with Deed on enough relevant metrics. It is also cripplingly slow and often just wouldn't do enough in time. One of the best things about Deed is and remains that it can just sit there in play and act as a Seal of token and animated land removal. Not many things deal with manlands effectively and with the power and popularity of the Adventures in Forgotten Realms man lands there is an improving argument for Deed in cubes, especially those packing a lot of Mox and other mana artifacts.
Engineered Explosives 5/10
A more selective Pernicious Deed that only hits CMC = to X rather than everything upto and including X. This still hits tokens but no longer takes out lands. Generally this is more playable but less powerful than Deed. It is used more of an out to awkward things and situations more than it is used as a good card. It either isn't that mana efficient or it is a bit situational making it something you typically want to have a reason to play. Triomes have made Explosives better as decks often now have access to more colours than they are. That being said, you rarely need explosives in decks that are three or more colours and those that are just the one colour do not give you enough options on your explosives. As such I find that while the card feels like a great include for cubes it rarely winds up getting enough play or doing quite enough in games. It is just kind of insurance and if things are going well that is something you don't need or want to need.
Powder Keg 4/10
Ratchet Bomb 3/10
These are yet more examples of Deed and Explosives style cards that continue in the trend of being increasingly playable but decreasingly powerful. While these can both be mana efficient removal tools it is pretty hard to have either do so in a useful way due to how long it takes to charge them up sufficiently. Kill your thing in four turns really isn't going to cut it. This means you really only want to use these cards on 0 and 1 CMC cards, ideally the former. This makes them pretty good against tokens and some explosive artifact strategies as well as some of those really polar decks like elves or 8-whack that overload on 1 CMC permanents. Overall Powder Keg is the better card as it deals with artifact and creature lands. Killing planeswalkers and Enchantments is all well and good but they are on average much higher CMC cards and a much less common type and thus far less useful and efficient to remove with cards like this. Pernicious Deed is more powerful than Keg but it rated the same as Deed is that much less playable being gold and not colourless. And proper colourless at that, none of than sunburst crap.
Partial (modal)
Damn 8.5
A fascinating card that is rather hard to rate as it is somewhat five different cards in one. Are you even split white and black, perhaps in a kind of midrange archetype? In which case Damn is about as good as it gets. Are you mono black or mono white, mostly a black deck but with the ability to produce some white mana, or indeed a heavier white deck with some capacity to produce black mana? Damn is playable in all these settings but has differing power levels, different optimal archetypes, and most curiously of all, can wind up competing with entirely different cards on different points on the curve as well. In the sweet spot Damn is the perfect removal spell allowing you to kill one problem card without harming your own board or deal with everything to recover a bad situation. It is even more rounded of a removal tool than Winds of Abandon! It is good while you are ahead or behind, it is hard to play around, and it has an impressive range. The only thing keeping this off being a 9+ rated card is that it is quite an intensely gold card. Much of the play it does get are outside this sweet spot where it either tends towards the very acceptable Wrath of God on the white end of the spectrum or the slightly less impressive but none the less decent Walk the Plank as you tend towards black.
Sweltering Suns 7
A nice clean and simple red mass removal spell. There are many like this with their various pros and cons where you get to pay three to deal three to everything. Indeed there are plenty of other X damage for X mana cost in red and indeed actual X spells which reduce this efficiency in exchange for some flexibility. While many of these are good I have always found them to be just that little bit too situational for my liking. As such the one with cycling on it has always wound up getting the most play as you can afford to play it that bit more speculatively. It is an option rich card you can play in an aggressive deck to give you that edge against some matchups without being too severe of a cost. I play this in most midrange and control red decks and it creeps in to the odd aggro one here and there as well. It remains significantly more mana efficient than the likes of Starstorm too, which is important as mass removal is there to recover tempo. If you have to wait or leave the bigger things still in play you are not doing the job required of you. Instant is lovely on mass removal but it cannot come at the cost of the main functionality which cards like Starstorm entirely do in this modern era of high tempo and pushed dorks. Sweltering Suns also hits all kinds of dorks which helps keep it playable. Plenty of red mass removal miss artifacts or flyers and this winds up being a big deal when these kinds of cards are already on the fringes.
Slagstorm 4
Before Sweltering Sun this was my go to modal red mass removal spell. You could play it in aggro as it dealt three to face and thus was never dead. Thing is, it still kind of sucks. One half very situational and the other just very inefficient. You were only solving the narrow issue for aggro decks which were not really in the market for mediocre mass removal anyway, and you were not even solving it well. Midrange decks want a more playable mass removal spell and they are certainly not at all impressed by 3 to each players face mode even if the control players are even less impressed with it!
Burn Down the House 8.5/10
A bigger better Storm's Wrath. While the scale up from four to five does halve the number of cards it doesn't outright kill while retaining the ability to kill on curve dorks, even on the draw, it is still a nerf compared to Storm's Wrath. Mass removal wants to be able to quell an early onslaught and for that low cost is the best thing. What makes Burn Down the House so good is the modality which Storm's Wrath lacks and Sweltering Suns attempt is laughable in power level by comparison. Making three devils for 5 mana is actually just good in my cube. It has so much fantastic synergy with so very many great cube cards (Goblin Bombardment, Torbran, Purphorus etc) and is pretty decent all by itself. It is a lot of damage, it has immediate impact, it is hard to play around. Mass removal is one of the most powerful things in the game, it is kept somewhat fair by the tension it has on over extending and because that makes it quite situational. When you slap a pretty good all round threat mode on your mass removal you remove these tensions than can make it fair. Oh, you held back so my five to everything didn't kill you? Well, turns out these three devils now kill you instead. Whoops.
Elspeth, Sun's Champion 7/10
Probably closer to an 8/10 card in general but in the context of mass removal we need to be less generous. Six mana is a lot for a mass removal spell and this effect only kills about 15% of creatures in my cube. Further to that it is very rare for it to kill more than one dork of the opponents. Suffice it to say that you usually win when you lay Elspeth and -3 her and just kill the one dork, you really struggle to lose if you hit multiple of theirs! Just by virtue of having a powerful walker down and handling their powerful threats you are in a winning position. Elspeth is more of a super 187 dork that will randomly win you some games that looked very done. One of the coolest things I have seen done with Elspeth is using buffs on opposing dorks so that the -4 will kill them. She is mostly here on a technicality, she can act as a one sided Wrath of sorts but that isn't why you are playing her, she is just good in general and randomly is sometimes really really good in a way that qualifies her for this list.
Chandra, Awakened Inferno 6.5/10
This is probably a better mass removal effect than Elspeth but it is generally not quite so useful of a card. Much of this is down to the cards in the respective colours and the types of archetype you find them in. Chandra is more likely to find bigger dorks a problem because red as a whole does, and so being able to do a dodgy Sweltering Sun for twice the price isn't winning any awards. Elspeth handles little things by making loads of 1/1s which is a fine thing to do if they don't have threatening stuff you need to answer. Yes, it is nice to have option rich planeswalkers and it is a fine enough option that comes up useful but the mass removal here certainly isn't why you are playing the card. Mostly I think this is played as inevitability that happens to have some failsafe modes.
Austere Command 3/10
Back when this was a somewhat new card it was all the rage. It was a versatile Wrath that answered most things you were likely to need it to and it would often leave you ahead once played. As time went on a six mana sorcery speed answer came too late. Missing walkers and usually needing to hit both dork modes when under pressure did for this once top tier mass removal tool. Now it simply isn't a practical solution to anything and is rarely better than a Wrath of God for 150% of the price.
Farewell 6/10?
As of writing this I have done no meaningful testing of this card but it does look like a good attempt at updating Austere Command. One or more modes gives this more modality and more raw clearing power than Command although the inability to split the creatures into big and little ones does remove a lot of the ability Austere Command gave to leave yourself ahead after Wrathing. Exile quality removal adds a big kick to this as well making it quite a strong answer to a wide array of tedious and tenacious problem cards. Gods, upon death triggers, all that awkward stuff gets swept away nicely with this big happy exile card. Graveyard disruption is also always welcome when you feel like you are getting it for free as is the case here. If this were an instant the card would be outstanding, at sorcery it has a chance but it likely still a bit on the slow side for most cubes. Perhaps if it could also take out walkers then I could get past the sorcery side of things but probably not even then. As a technicality it probably shouldn't be on this list as when Wrathing it is neither partial or one-sided! It is complete and symmetrical. The card just gives the illusion of qualifying for this list due to the similarity to Austere Command and by virtue of being modal mass removal. Ultimately that is semantics. Farewell is a mass removal spell, it is a Wrath plus, and it may, like so many of the cards on this list, be used to less than its maximum capacity to engineer a favourable outcome. As such, and rather self evidently, I deem it worthy of discussion here! Certainly if you were in the market for a big cover all answer card I would look to this and Hour of Revelation first and foremost.
Limited
Fire Covenant 9/10
This is limited in the sense that under most circumstances you do not have an unlimited life total. Beyond that this is effectively unlimited. Toxic Deluge has a lot of similarities to this card and yet I placed that in the partial variable Wrath section despite having near identical costs to this. The main difference is the top end scaling of both cards. The average life you have to pay to clear your opponents board as the game progresses over time looks fairly different with these two cards. They both go up as the likelihood of facing a big tough dork increases as the game goes up but it is a far sharper increase for Covenant as you have to pay a life for each toughness in play and not just the highest toughness in play. The wider an opponent goes the costlier it is for Covenant in terms of life and that in turn makes it rather more limited in how much you can afford to use it. It is a much more self limiting card than Deluge. Even so, Fire Covenant is absolutely outstanding with plenty of perks over Toxic Deluge so as to keep things interesting. Covenant is instant speed which is nutty good for a three mana mass removal tool and the number of blow out plays it can do as a result is a bit too much frankly. It is also fully targetted making it the most one sided card here. So often it is just three mana and an irrelevant amount of life (as a consequence of how brutal the effect is) to utterly reset the tempo of the opponent, typically trading about three for one on both cards and mana spent. One drop, two drop, Covenant is the safest win against anyone fool enough to curve with creatures in the first three turns short of those with the right protections! Covenant is good in control decks but it is unreasonable in the aggressive and midrange decks that can best exploit the one sided nature of the card while at the same time stomaching the high life cost it comes with.
Wretched Confluence 8/10
The hitting power of this removal spell is pretty poor. It rarely seems to gain mana advantage when used even when all three modes are -2/-2. Yes, it can three for one but typically when it does it is killing relative chaff. Confluence is good as a mass removal spell not because of the power it has but the broad convenience. It is never dead and will do what you need it to in a pinch. It can be a much more devastating one sided Wrath if used in conjunction with a combat step. It can be used to kill one small pesky critter without feeling like you have wasted a big card as you can use the remaining modes on vaule. It has a lot of power, a lot of safety in the use of, and is so rarely dead that it seems to end most close games in which it is cast. It either abruptly ends the fight for board control or it provides too much value to compete with on that front. Rounded card with a consistently high performance.
Finale of Eternity 8/10
This lacks a lot of the convenience of Confluence but it makes up for it in raw killing power. Where Confluence struggles to gain a mana advantage this rarely fails to do so. It has such a high ceiling and power level that even when you are taking out two dorks rather than just one it feels like great value. This thing has to have one of the highest cast to win ratios in my cube at present. Note that this is very much not the same as having a high win percentage when in opening hand or when in a deck. It also kind of needs a devastating ceiling as it is both a polar and a situational card. It is typically underwhelming against control decks and it can sit in hands offering little to no utility more so than most other cards I am happy running in cube. Very much a card to be feared and respected. One of those cards that seems unimpressive in a powered cube world of fast mana, massive fatties, and hard to interactive with combos, but as you move towards a more tempo and creature driven unpowered format cards like Finale of Eternity bubble to the top of the pile.
Arc Trail 8/10
Forked Bolt 7/10
In the way that Finale of Eternity or Winds of Abandon can just come out late and utterly end the game on the spot these little red beasts can come out early and nip games in the bud. If I can kill two things in the first few turns of the game with either of these cards then the odds of me losing that game are stunningly low. Arc Trail in particular leads to those plays that make spectators wince, like they have just watched some leg breaking tackle in the sport ball. It doesn't matter whose the Llanowar Elf and Tireless Tracker are, when an Arc Trail sends them to the bin it hurts for all. These cards more so than any others have caused a meta shift away from too many one toughness dorks. Although make no mistake Plague Mare, Lava Dart, Chainwhirler, Plague Mare (and the new spectacle one), and Wrenn and Six all contribute to toughness bias in cube.
Fury 9/10
Pyrokenesis 4/10
Here is a potent example of modality making cards powerful. Pyrokenesis is playable but not great, Fury is broken. The pitch mode is arguably better on Pyrokenesis simply due to being instant. It would be closer to the ability to hit planeswalkers but on a pitch spell the instant speed is at its most valuable. You are aiming these spells at dorks most of the time as it is due to there being more of them and the fact that when the dorks are dead it gets a whole lot easier to attack the walkers to death! Fury is simply that much better because for five mana you can get a high tempo disruptive two or better for one pro active threat. It is like a Massacre Girl that needs no setup and is entirely one sided! Pyrokinesis simply doesn't deliver on the six mana side of things meaning it isn't modal in a good way and unless you are able to get good value from the pitch mode the card is just kind of bad. Forcing yourself into a position to potentially eat a two for one or have a dead card.
As you can see, a lot of highly rated cards on this list. One sided mass removal is where it is at! Or at least when you can get it on the cheap or at least on cards that can be otherwise used relatively cheaply.
