God-Pharaoh's Faithful triggers, causing you to gain life.
When Acererak enters, its first ability and Carnival of Souls trigger.
Resolve the Carnival of Souls trigger, causing you to add and lose 1 life.
Resolve the Acererak trigger, returning it from the battlefield to your hand, and venturing into Lost Mine of Phandelver.
Repeat.
This clever loop relies on casting Acererak the Archlich for a single black mana, triggering its enter-the-battlefield ability to immediately bounce itself back to your hand while venturing into the dungeon (specifically looping *Lost Mine of Phandelver*). Carnival of Souls fuels this endless cycle by refunding your mana investment at the modest cost of a life point each time Acererak enters, turning a self-returning creature into a continuous engine. Meanwhile, God-Pharaoh's Faithful turns every single casting iteration into a net-neutral life exchange, keeping you afloat as you grind through the dungeon. Finally, Hamza, Guardian of Arashin scales with the chaos, leveraging the creature enters-the-battlefield triggers to make subsequent spells even cheaper and cementing an unstoppable engine.
