Acererak the Archlich (AFR) / Extended Art

When Acererak the Archlich enters the battlefield, if you have not completed Tomb of Annihilation, return Acererak the Archlich to its owner's hand and venture into the dungeon.
Whenever Acererak the Archlich attacks, for each opponent, you create a 2/2 black Zombie creature token unless that player sacrifices a creature.
