Mecha'thun Priest is a priest 
Mecha'thun deck which primarily focuses on drawing a one-turn kill combo with the Mecha'thun while aggressively draw and destroy from the deck with cards such as Hemet, Jungle Hunter and Acolyte of Pain.
The combo in this deck requires having no other cards in the hand and deck. The player needs to play Reckless Experimenter, Coffin Crasher, and two Ticking Abominations in order with only Mecha'thun in hand, when the turn ends, the Coffin Crasher dies and pulls Mecha'thun. while the two Ticking Abominations will kill all minions on the player's side of the board. The Priest Mecha'thun decks are often used over other classes when it comes to Mecha'thun decks since none of the combo pieces are destroyed by Hemet, Jungle Hunter.
To provide an extra chance of survival, some variants of this deck utilize the priest quest Awaken the Makers and several deathrattle minions.
