Here are my thoughts: add a single Necrotic Ooze, add one to two Jarad's Order, and remove two Grim Poppets and one other card (probably a Villainous Wealth.)


Also Rustrazor Butcher is an oddball card considering its the only /red/ card in the deck, I say it adds little and complicates the deck, its a tough call though.


Now look at the combos you can pull off with a well timed Jarad's Order:
-Should you have either a Devoted Druid or a GrimPoppet in the graveyard, you then search for the other and put it in the graveyard and grab a Necrotic Ooze, everything on the other field dies instantly when it hits the battlefield.
