The goal of this Hearthstone Mecha'thun Warlock OTK combo deck is to use Shadow Hunter Vol'jin combined with Mecha'thun!
We do this by emptying our deck and playing a 1 or 0 cost minion, Vol'jin to pull out Mecha'thun, and Cataclysm to win the game! Make sure Mecha'thun is the last remaining minion in hand on the combo turn otherwise Vol'jin can pull the wrong minion!
Super fun meme deck! Good luck!
