Relentless Dead + Carnival of Souls + Rooftop Storm + Zulaport Cutthroat + Carrion Feeder

Relentless Dead

Carnival of Souls

Rooftop Storm

Zulaport Cutthroat

Carrion Feeder

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 Carrion Feeder 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 Carrion Feeder ability, putting a +1/+1 counter on it.
9. Repeat.

This loop turns your graveyard into an infinite engine by leveraging Rooftop Storm to cast Zombie spells completely for free. As Relentless Dead repeatedly enters and exits the battlefield, Carnival of Souls provides the black mana needed to bounce it back to your hand with its own death trigger, offsetting the life loss effortlessly through Zulaport Cutthroat's life-draining triggers. Meanwhile, every cycle feeds Carrion Feeder a fresh sacrifice, stacking up limitless +1/+1 counters while draining your opponents out of the game in one decisive sweep.
