Bernokk, the Undead Storm

Trample, haste, ward {2}

Bernokk, the Undead Storm's power and toughness are each equal to the number of multicolored creatures you control.

When Bernokk enters, you may exile any number
of creature cards from your graveyard. If you do, create that many 2/2 blue and black Zombie Spirit creature tokens with haste.
