Warlock
Plays like a normal evenlock but with few more board clears. goal is to survive in the end and win normally, or launch Mechacthun When u have no cards left.
Ok so when u have Mecha'thun on your hand your goal is get it to 8mana with Galvanizer x2
Mecha’thun + Bloodbloom +Cataclysm = Epic win
then when u have no cards left u can make This crazy combo: First play mechacthun at 8mana. Then play bloodbloom with your 2 remaining mana and finish with Cataclysm = victory.
