Iraxxa, Empress of Mars + Squee, the Immortal + Phyrexian Altar + Stone Calendar

Iraxxa, Empress of Mars

Squee, the Immortal

Phyrexian Altar

Stone Calendar

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 Phyrexian Altar twice by sacrificing Squee and the Alien Warrior, adding .
4. Repeat.

This clever loop turns Squee, the Immortal into an endlessly renewable resource by utilizing his ability to be cast straight from the graveyard or exile. With Stone Calendar discounting his mana cost to just {R}{R}, you can repeatedly cast him to fuel Iraxxa, Empress of Mars's Paradox ability, which floods the board with 2/2 red Alien Warrior creature tokens every time a spell is cast from outside your hand. Finally, Phyrexian Altar acts as the engine's heart, letting you sacrifice both Squee and the newly minted tokens for the exact mana needed to keep casting him on an infinite loop.
