Mecha'thun Druid is a Druid deck type. It features Mecha'thun as its win condition, using cards like 
Branching Paths, Ultimate Infestation, and Nourish to quickly draw through the deck, finishing by playing Mecha'thun, followed by Innervate and Naturalize once the deck is empty to instantly kill the opponent.
With the release of the Forged in the Barrens expansion, one of the primary ways of drawing through the deck and destroying Mecha'thun is to use the combination of Lady Anacondra and Celestial Alignment, allowing the player to draw through the deck almost instantly once the effects of both cards are in play.
