Evil Value is the name of this game, Grigori combos with the vast majority of minions in this deck. Draw engines are the omphalos, and the book of the dead for recursion. Mulligan sites hard for an a Den of evil or at least 1 tower. Turn 2 morgana in a den of evil is my favorite early game play with this deck. It can pop off in a single turn by turn 4. In game Example: turn 3 put den of evil for your 3rd mana and play greater blood demon, turn 4 you can play something like road to perdition pump the demon to 7 power and grapple shot to the avatar for an explosive early game lead… 14 damage!! Many examples like that especially if you get Grigori out early , use him as an early game blocker then attack with an evil minion pay the 2 mana and add Grigoris power and spell caster ability to their text box. My favorite example is with dapryll vampire/ Grigori. That is a 6/6 spell caster with airborne and life gain against units!
