To my surprise, in Standard Midrange Hunter with a few dragons. I really enjoy the swamp dragon theme they've added to Hunter. Hunting Mastiff, Huntmaster Shaw and the Poisonous 5-mana dragon add some nice possibilities too. The secret that summons a 6/6 rat gets triggered a lot. Even just one secret makes a lot of difference in tempo.
In Wild, Dragon Priest, Overload Shaman and a budget demonlock. (Mostly taking damage, quick heals and buffing demons) I tried a budget Cubelock but I really dislike the playstyle.
