I originally started this with 4 Hardened Scales, focusing on taking advantage of megamorph to fatten my creatures even more, but I took them out for Goblin Rabblemaster to present a more immediate threat. I also ran 2 Genesis Hydra, but replaced them with the 2 Collected Company when Scales was removed. The most iffy card in the maindeck, I think, is Ire Shaman. I like it as a cheaper way to bring back Deathmist Raptor while also possibly nabbing another playable. Maybe I should take one out and add another land?

The biggest problems I predict with this deck are dragons and devotion, both of which are very heavily played at my LGS. For this I side in Plummet and Hornet Nest, which I can burn for tokens if things get ugly. Arc Lightning clears out early ramp against devotion, and the rest of the SB is the basic kit vs control, heroic, tokens etc.
