Iraxxa, Empress of Mars + Squee, the Immortal + Thermopod + Umori, the Collector

Iraxxa, Empress of Mars

Squee, the Immortal

Thermopod

Umori, the Collector

How it works

1. Cast Squee from your graveyard or from exile by paying .
2. Iraxxa triggers, creating a 2/2 Alien Warrior creature token.
3. Activate Thermopod's second ability twice by sacrificing Squee and the Alien Warrior, adding .
4. Repeat.

This loop relies on casting Squee, the Immortal from exile or your graveyard repeatedly, turning every iteration into a cascade of value. With Umori, the Collector naming "Creature," Squee’s casting cost is discounted to just two red mana, perfectly matching the mana generated when Thermopod sacrifices both Squee and the Alien Warrior token created by Iraxxa, Empress of Mars's Paradox ability. Because Iraxxa triggers whenever you cast a spell from anywhere other than your hand, every recursion of Squee supplies a fresh fodder creature for Thermopod, fueling an endless cycle of sacrifices.
