Even I find it difficult to believe that this deck started out with Cumber Stone, there it is. Four of those, along with a full complement of Etherium Sculptors and a pair of Phyrexian Metaphorphs, comprise the 10 blue spells. I went with some cheap arcbound cards, a couple copies of carnage alter to get drawing, a few ways to bulk up and hit hard, and Stuffy Doll to add to ground defenses. Basically, this is designed to be a (relatively) fast deck that can grow, literally, by dying. The (4)/6/12/5/9/3/1 curve stretches out to the 6-spot, but still only averages 2.55, and the use of loci and Etherium Sculptor make the real cost lower.
