Jepetto OTK Warlock! You’re trying to draw Alex and Malygos with Jepetto, then kill your opponent with Bane of Doom + Soulfire for 16 damage. You can also use Hellfire if you have at least 9 health to spare. Plot Twist is there to save you if you draw your combo pieces before Jepetto, or just to help mulligan your hand if you need things to play.
Call of the Void, Dark Possession, Rafaam’s Scheme and Fiendish Circle are all spells that generate minions. You need to be proactive on the board to try and survive. Curse of Weakness is basically like a Frost Nova, it can stall for a turn or help your creatures trade and survive.
