Squee, the Immortal + Mana Echoes + Ashnod's Altar + Prismite

Squee, the Immortal

Mana Echoes

Ashnod's Altar

Prismite

How it works

1. Activate Ashnod's Altar by sacrificing Squee, adding CC.
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 twice by paying 4, adding .
5. Repeat.
6. If you control four or more Goblins, this combo nets infinite mana.

This clever loop relies on Squee, the Immortal's unique ability to be cast directly from the graveyard, effectively turning it into a recurring resource for your sacrificial engines. When you feed Squee to Ashnod's Altar, you generate colorless mana while sending the Goblin back to the graveyard to be recast. Mana Echoes supercharges this loop by tapping into Squee's creature type, providing an escalating burst of colorless mana with every iteration as long as you have a few other Goblins on the board. Finally, Prismite acts as a reliable color filter, converting your massive colorless surplus into whatever colored mana you might need to keep casting Squee and net infinite resources.
