Acererak the Archlich + Carnival of Souls + Semblance Anvil + Tablet of the Guilds

Acererak the Archlich

Carnival of Souls

Semblance Anvil

Tablet of the Guilds

How it works

1. Cast Acererak either from your hand or from the command zone by paying plus commander tax, if applicable.
2. Tablet of the Guilds triggers, causing you to gain life.
3. When Acererak enters, its first ability and Carnival of Souls trigger.
4. Resolve the Carnival of Souls trigger, causing you to add and lose 1 life.
5. Resolve the Acererak trigger, returning it from the battlefield to your hand, and venturing into Lost Mine of Phandelver.
6. Repeat.

This clever loop transforms Acererak the Archlich into a self-sustaining engine by perpetually dodging the Tomb of Annihilation to instead continuously venture through the Lost Mine of Phandelver. To make this repeatable, Semblance Anvil discounts Acererak the Archlich down to a single black mana, which is conveniently refunded every time Carnival of Souls triggers off the lich entering the battlefield. Meanwhile, Tablet of the Guilds neatly offsets the life lost from Carnival of Souls by padding your total with every cast, turning an infinite loop of dungeon rooms into an absolute victory.
