Squee, the Immortal + Mana Echoes + Phyrexian Altar + Prismite

Squee, the Immortal

Mana Echoes

Phyrexian Altar

Prismite

How it works

1. Activate Phyrexian Altar by sacrificing Squee, adding .
2. Cast Squee from your graveyard by paying 1.
3. When Squee enters the battlefield, Mana Echoes triggers, adding C for each Goblin you control.
4. Activate Prismite by paying 2, adding .
5. Repeat.
6. If you control four or more Goblins, this combo nets infinite mana.

This delightfully resilient loop relies on Squee, the Immortal's unique ability to be cast directly from your graveyard, allowing it to become a renewable sacrifice fodder for Phyrexian Altar. As Squee repeatedly enters the battlefield, Mana Echoes triggers to flood your pool with colorless mana, scaling rapidly if you happen to control other Goblins. Because Mana Echoes only generates colorless energy, Prismite steps in as an essential color converter, filtering that excess into any color you desire. Once you have at least four Goblins on board, the mathematical tipping point is reached where the mana produced outpaces Squee's casting cost, fueling an infinite engine of sacrifices, storm count, and colored mana.
