Awesome! Bravado , Pennon Blade , Door of Destinies , Adaptive Automaton , but I'm not telling you anything you don't already know! Also maybe Dogpile ? Anyway big +1!

I like each of your suggestions Aelorith, as they really do fit well with a single creature-type deck. I actually meant to include Bravado in the first place but somehow had forgotten about it. For everything else, I really wanted to stay within the 2 mana cost range to see how it works. So who knows, after some testing I may decide to put some more of these in. Great suggestions!

Also if you're really searching for a winning card Phyrexian Vault does wonders!

I highly recommend Skullclamp, it would boost the deck to a whole new level.

Maybe splash green for Assault Formation?
