Good luck keeping cost down, Damnations ($15), Extirpates($15), Thoughseizes($20), Dark Confidants($15), and Pithing Needles($20) are gonna rape your wallet BAD.
I'd ask Kyler and Kolt for tips on this build, they're pretty pro for this sort of deckbuild. Kinda wondering what the husk is doing there though. Did you mean Nantuko Shade? Also, Nixathid (I can't spell this thing's name, the black creature from Conflux) looks pretty good to go with the massive hand dumping.
