Warren Soultrader + Gravecrawler + Auriok Champion

Warren Soultrader

Gravecrawler

Auriok Champion

How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing Gravecrawler, creating a Treasure token.
2. Activate the Treasure by tapping and sacrificing it, adding .
3. Cast Gravecrawler from your graveyard by paying .
4. When Gravecrawler enters, Auriok Champion triggers, causing you to gain 1 life.
5. Repeat.

This loop operates on a clever resource conversion, using Warren Soultrader to transform a living creature into a Treasure and a fresh source of life. Because Gravecrawler can be repeatedly cast straight from your graveyard as long as you have a Zombie friend around, the mana generated by sacrificing that Treasure covers the re-entry cost entirely. Meanwhile, Auriok Champion sits safely on the battlefield providing a steady cushion of lifegain every single time Gravecrawler returns, neatly offsetting the life you pay to the Soultrader and allowing you to loop the process indefinitely.
