Apparently I missed this one on the MH2 reviews. Perhaps I thought it was a reprint somehow? This card is great. A really useful little removal spell that can help enable some other synergies. The flexibility on this latest iteration of Bone Splinters is just enough to finally make this kind of card playable. This comes as a little bit of a surprise as it is a sorcery but being able to take out the main two types of threat for one mana with the additional cost of your choice is not only a burden we can stomach but often a perk.
The card is somewhere around the Baleful Mastery and Bloodchief's Thirst mark. All three kill walkers and dorks and all three have potential cost incursions. Compared to Thirst Bone Shards scales rather better and can offer big midgame tempo swings. Early on the Shards are generally worse but that hasn't stopped Path to Exile being a premium answer for many a year! Thirst is a card that covers you but rarely pulls you ahead, it is a buoyancy aid at best. A necessary evil from time to time. Bone Shards however can be game winning thanks to the low cost throughout its range.
