Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Essence Warden

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Essence Warden

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, Essence Warden 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, Essence Warden triggers, causing you to gain 1 life.
9. Resolve the Warren Soultrader ability, creating a Treasure token.
10. Repeat.

This crafty loop lets you endlessly sacrifice and resurrect your creatures, fueled entirely by the life gained from Essence Warden offsetting Warren Soultrader's life-payment cost. As Nether Traitor bounces back and forth into the graveyard, its death triggers Sek'Kuar, Deathkeeper to churn out hasty Graveborn tokens that feed right back into the engine. Meanwhile, the treasures produced by Warren Soultrader supply the black mana needed to pay Nether Traitor's recurrence cost, resulting in an endless cascade of sacrifices, artifacts, and life.
