Sek'Kuar, Deathkeeper + Warren Soultrader + Nether Traitor + Guide of Souls

Sek'Kuar, Deathkeeper

Warren Soultrader

Nether Traitor

Guide of Souls

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, Guide of Souls triggers, causing you to gain 1 life and get E.
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, Guide of Souls triggers, causing you to gain 1 life and get E.
9. Resolve the Warren Soultrader ability, creating a Treasure token.
10. Repeat.

This recursive loop turns Warren Soultrader into an absolute engine by bouncing Nether Traitor in and out of the graveyard, perpetually cycling them by paying life and black mana. Every iteration is cushioned by Sek'Kuar, Deathkeeper, which replaces your fallen threats with hasty Graveborn tokens to keep the sacrifice fodder flowing. Meanwhile, Guide of Souls watches the endless parade of entering creatures to constantly pad your life total and stockpile energy counters.
