The goal of this Hearthstone Mecha'thun Warlock OTK combo deck is to use Millhouse Manastorm combined with Rin the First Disciple!
We do this by playing Rin, Treachery, and Millhouse. The opponent will then be able to play all of the Seals and Azari in 1 turn to destroy our deck! We then play Mecha'thun and Cataclysm for the OTK!
Super fun meme deck! Good luck!
