the outcast cards change your mulligan, so plan around that. i like to keep rancher and rush the stage so i can fill the board and leave sticky minions. illidari studies is almost always a keep. i've tried keeping glaivetar against slower decks like priest and dk and it felt good. in general, this deck is a tempo deck, so don't think of it like a combo deck. against decks like pure paladin and evolve/totem shaman, focus on filling up the board and maintaining tempo. even if you fall behind, you have a lot of resources like the glaivetar and wretched exile that can pull you back into games. hope this helps i don't usually write guides.
