Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Hinterland Sanctifier

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Hinterland Sanctifier

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

This elegant loop turns a simple sacrifice engine into an infinite life and treasure machine. By using Warren Soultrader to sacrifice Nether Traitor, you feed Sek'Kuar, Deathkeeper's triggers to spawn a hasty Graveborn token, which instantly pays back the life spent thanks to Hinterland Sanctifier. The resulting Treasure tokens then fuel Nether Traitor's own resurrection ability to restart the whole cycle.
