Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Angelic Chorus

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Angelic Chorus

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

This loop turns your graveyard into a relentless engine of sacrifice and resurrection, anchored by Warren Soultrader as the ultimate outlet to turn your creatures into raw material. By feeding Nether Traitor to the Soultrader, you trigger Sek'Kuar, Deathkeeper to immediately replace the fallen spirit with a hasty Graveborn token, which conveniently offsets the life payment because Angelic Chorus is watching every single creature arrive with a burst of healing. That very same Graveborn can then be sacrificed to Warren Soultrader to generate the black mana needed to trigger Nether Traitor's own resurrection clause, looping the two creatures endlessly while spinning off infinite Treasures, life, and death triggers in the process.
