A-Acererak the Archlich

Not yet bracketed (or genuinely unplaceable).

3-mana 5/5 Zombie Wizard that self-bounces and ventures into Tomb of Annihilation until completed, then stays to generate one Zombie token per opponent on each attack. Signature in Brawl zombie-token shells that can leverage the dungeon-completion payoff. The slow ETB loop is a real setup cost, but once Tomb of Annihilation is completed Acererak becomes a powerful repeatable token engine in multiplayer-style Brawl.
