Nested Ghoul + Terror of the Peaks

Nested Ghoul

Terror of the Peaks

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 Terror of the Peaks, dealing damage equal to the Phyrexian Zombie's power to Nested Ghoul.
5. Repeat from step 3.

This elegant loop relies on giving Nested Ghoul indestructible so it can endlessly absorb damage without perishing. When a source damages it, Nested Ghoul triggers to create a 2/2 Phyrexian Zombie token, which immediately brings Terror of the Peaks into the equation. The arrival of this new token triggers Terror of the Peaks to deal damage equal to the token's power right back to Nested Ghoul, restarting the entire cycle to continuously flood the board with infinite creature tokens and repeated creature ETB triggers.
