Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Ajani's Welcome

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Ajani's Welcome

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, Ajani's Welcome 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, Ajani's Welcome triggers, causing you to gain 1 life.
9. Resolve the Warren Soultrader ability, creating a Treasure token.
10. Repeat.

This elegant engine feeds on sacrifice, turning the cyclical doom of Nether Traitor into an endless bounty by leveraging Warren Soultrader to convert creatures into Treasure tokens. As Nether Traitor and the Graveborn token created by Sek'Kuar, Deathkeeper trade places in and out of the graveyard, Ajani's Welcome effortlessly offsets the life cost required to keep the Soultrader churning. Because the black mana produced by the Treasure covers the revival cost of Nether Traitor, the loop sustains itself indefinitely, generating infinite resources and death triggers along the way.
