Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Kor Celebrant

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Kor Celebrant

How it works

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

This elegant loop turns Warren Soultrader into an absolute engine of life and treasure by continuously recycling creatures through the graveyard. When you sacrifice Nether Traitor to Warren Soultrader, Sek'Kuar, Deathkeeper immediately steps in to replace your fallen shadow creature with a hasty 3/1 Graveborn token. That token's arrival triggers Kor Celebrant to gain you a life, cushioning the life payment required by Warren Soultrader, while the Treasure token it produces pays for Nether Traitor's own recursive resurrection ability. By bouncing sacrifice fodder back and forth between Nether Traitor and the Sek'Kuar-generated Graveborn, you generate an endless cascade of death triggers, treasures, and life.
