Relentless Dead + Carnival of Souls + Rooftop Storm + Zulaport Cutthroat + Viscera Seer

Relentless Dead

Carnival of Souls

Rooftop Storm

Zulaport Cutthroat

Viscera Seer

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 Viscera Seer 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 Viscera Seer ability, causing you to scry 1.
9. Repeat.

This elegant loop turns the graveyard into a revolving door by leveraging Rooftop Storm to cast Relentless Dead for free. As Relentless Dead enters the battlefield, Carnival of Souls provides the exact black mana needed to fuel its own death trigger, while Viscera Seer acts as the reliable sacrifice outlet to send it back to the graveyard. Meanwhile, Zulaport Cutthroat turns every iteration of this gruesome cycle into a draining engine that steadily drains your opponents while padding your life total.
