Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Relic Vial

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Relic Vial

How it works

1. Activate Warren Soultrader by sacrificing Nether Traitor and paying 1 life.
2. When Nether Traitor dies, Relic Vial and Sek'Kuar trigger.
3. Resolve the Relic Vial trigger, causing you to gain 1 life and each opponent to lose 1 life.
4. Resolve the Sek'Kuar trigger, creating a 3/1 Graveborn creature token.
5. Resolve the Warren Soultrader ability, creating a Treasure token.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Activate Warren Soultrader by paying 1 life and sacrificing the Graveborn.
8. When the Graveborn dies, Relic Vial and Nether Traitor trigger.
9. Resolve the Relic Vial trigger, causing you to gain 1 life and each opponent to lose 1 life.
10. Resolve the Nether Traitor trigger, causing you to pay to return Nether Traitor from your graveyard to the battlefield.
11. Resolve the Warren Soultrader ability, creating a Treasure token.
12. Repeat.

This loop sets up a self-sustaining cycle of sacrifice and resurrection, fueled by Warren Soultrader's ability to turn any creature into a Treasure and a life payment. Nether Traitor serves as the recurring sacrifice target, instantly pulling itself back out of the graveyard using the black mana generated by that Treasure. Meanwhile, Sek'Kuar, Deathkeeper ensures you get a 3/1 Graveborn token on the first death, providing the alternate fodder needed to keep the engine rolling on subsequent iterations. Finally, Relic Vial acts as your lethal payoff, turning every single one of these countless creature deaths into a steady drain of life against your opponents while padding your own total.
