This is a combo deck built around stalling long enough to execute the combo.
Past turn 10, play Karma, Clouddrinker, and Puffcap Peddler together, and then infinitely counterfeit and rummage (they will cost 0 and refill your hand), so you can literally do this infinitely in 1 turn). Try to use 2/3 of your counterfeits on rummage and 1/3 of your counterfeits on other counterfeits. End with your opponent having 1000+ mushrooms (literally the only limit is as fast as you can click)
