Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Dross Harvester

How it works

1. Activate Warren Soultrader by sacrificing Nether Traitor and paying 1 life.
2. When Nether Traitor dies, Dross Harvester and Sek'Kuar trigger.
3. Resolve the Dross Harvester trigger, causing you to gain 2 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, Dross Harvester and Nether Traitor trigger.
9. Resolve the Dross Harvester trigger, causing you to gain 2 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 recursive loop turns your graveyard and battlefield into an unstoppable engine, fueled by Warren Soultrader sacrificing creatures to generate Treasure tokens and life-managing resources. Nether Traitor makes this self-sustaining by paying its own resurrection cost with the mana from those Treasures, slipping right back into play whenever anything hits the graveyard. Meanwhile, Sek'Kuar, Deathkeeper converts every sacrifice into a hasty Graveborn token to keep the chain moving, while Dross Harvester acts as a vital life buffer that effortlessly offsets the life costs required to keep Warren Soultrader running.
