So I have a pretty sweet RDW (turn 3 wins) that's only problem seems to be if they can spam blockers or get turn three feast demons.

In answer, I have tooled in act of treasons/harness to clear them out and swing free. I have also added the hellraiser goblin to accelerate attacks and short cutter to assist with block prevention.I took out cacklers which may slow the deck not have having 8 turn 1 creature, but I think this fixes it by having a turn three take a blocker and hit you with blocker ability.
