Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Vengeful Bloodwitch

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Vengeful Bloodwitch

How it works

1. Activate Warren Soultrader by sacrificing Nether Traitor and paying 1 life.
2. When Nether Traitor dies, Vengeful Bloodwitch and Sek'Kuar trigger.
3. Resolve the Vengeful Bloodwitch trigger, causing you to gain 1 life and an opponent to lose 1 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, Vengeful Bloodwitch and Nether Traitor trigger.
9. Resolve the Vengeful Bloodwitch trigger, causing you to gain 1 life and an opponent to lose 1 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 elegant sacrifice loop uses Warren Soultrader as the engine to feed creatures into the graveyard continuously, fueled by the mana from the resulting Treasure tokens. Nether Traitor provides a self-recurring sacrifice target by using that black mana to slip right back onto the battlefield, while Sek'Kuar, Deathkeeper chips in with temporary Graveborn tokens to keep the fodder flowing. Meanwhile, Vengeful Bloodwitch stands watch over the entire cycle, turning every single death into an unstoppable drain of your opponent's life total until victory is yours.
