Mulligans
General Mulligans
Complete the quest with your Diretrolls, Shriek, and Cataclysm (worst case scenario use Doomguards) while also creating many Jeklik.
Aggro Mulligans
Board clears, big Taunts, etc
Control Mulligans
You just want to complete the quest and get that infinite value.
The goal of this deck is to discard Jeklik a large number of times, then use Soulwarden to add value back to your hand, which can include the DK if that got discarded. Complete the quest with Cataclysm, adding 2 Jeklik to your hand and infinite 3/2’s. Use Shriek, Defile, and Hellfire to clear aggro boards and Reckless Diretroll/Jeklik copies to taunt before you can man’ari out Voidlords and cube them.
