Nested Ghoul + Warstorm Surge

Nested Ghoul

Warstorm Surge

How it works

1. Give Nested Ghoul indestructible by any method.
2. Deal damage to Nested Ghoul.
3. Nested Ghoul triggers, creating a 2/2 Phyrexian Zombie creature token.
4. The Phyrexian Zombie enters the battlefield, triggering Warstorm Surge, causing the Phyrexian Zombie to deal damage equal to its power to Nested Ghoul.
5. Repeat from step 3.

This brilliant loop turns Nested Ghoul into an automated token factory by wrapping it in an unbreakable shield of indestructible magic. Once that foundation is set, a single outside ping triggers the Ghoul's damage-based creation ability to spawn a 2/2 Phyrexian Zombie. As that token arrives, Warstorm Surge immediately catches the creature's entry and hurls damage right back at the Nested Ghoul, triggering another token in an endless, self-sustaining cycle that generates infinite creature tokens and ETB triggers.
