Relentless Dead + Carnival of Souls + Rooftop Storm + Zulaport Cutthroat + Altar of Dementia

Relentless Dead

Carnival of Souls

Rooftop Storm

Zulaport Cutthroat

Altar of Dementia

How it works

1. Cast Relentless Dead by paying 0.
2. When Relentless Dead enters the battlefield, Carnival of Souls triggers, causing you to add and lose 1 life.
3. Activate Altar of Dementia by sacrificing Relentless Dead.
4. When Relentless Dead dies, its first and second abilities trigger, as well as Zulaport Cutthroat.
5. Resolve the first Relentless Dead trigger, causing you to pay to return Relentless Dead from your graveyard to your hand.
6. Resolve the second Relentless Dead trigger, choosing not to pay.
7. Resolve the Zulaport Cutthroat trigger, causing each opponent to lose 1 life and you to gain 1 life.
8. Resolve the Altar of Dementia ability, causing target player to mill cards equal to Relentless Dead's power.
9. Repeat.

This clever loop turns an endless parade of the undead into an unstoppable engine of destruction, all fueled by the cost-reducing magic of Rooftop Storm to cast Relentless Dead for free. As each iteration plays out, Carnival of Souls provides the exact black mana needed to fuel Relentless Dead's own resurrection trigger, turning life into a self-sustaining resource. Meanwhile, Altar of Dementia converts your endless sacrifices into a devastating milling win condition, while Zulaport Cutthroat drains your opponents out of the game simultaneously.
