I noticed hunter has ways to get allotta cards out of their deck, and thought it might work as Mecha’thun. Tracking and Subject 9 alone get 12 cards out of your deck. Master’s calls get another 6 out. Galvanizers let you play mechathun for 8 mana, which leaves 2 mana for arcane shot and hunter’s mark to finish off Mecha’thun.
Leave a comment with if u think it would work or not, as well as how you might tweak it.
