Literally speed ran the ladder to legend w/ this deck.
Against aggressive decks like Pally mulligan for Crescendo to take back board. Use damage offset early to stay in the game.
Against mid-range/control jam Insanity early (Insanity into 4 drop one of your best plays), and save damage offset for later.
Sludge guy provides some awesome plays - potential full heals and nice utility. Fracking is great for consistancy when you're drawing later on (but don't keep in opening).
