shamelessly took this from Savjz stream, not a competitive deck BY ANY MEANS, but just so much fun.
warrior control with very few minions, draw most of your deck, swap deck with opponent. By this point your deck has 1 or 2 cards left. Play explore un'goro, replace all of his cards with 1 cost discover card.
By this time either he fatigures cause you left him with nothing, or he plays ransom and get his deck back. Play skulking gheist, destroy his entire deck.
Play dead man's hand to keep you out of fatigure. Make sure you keep removal or massive armor gains to deal with the end of the game.
Watch as the opponent is confused as fuck as to what just happened.
