Today I ran this deck at a local Legacy mini-tourney, going 2-2.
I won dredge (!!!) with my ultra hate postboard with 2x Surgical Extraction, 2x Relic of Progenitus, 2x Engineered Explosives along with my already considerable md hate.
I lost to RUG delver rounds 2 & 4 with some subpar hands that did not deal with the onboard threats.
I won GW built-better-than-hate-bears-but-somewhat-still-hate-bears deck.
