Squee, the Immortal + Mana Echoes + Ashnod's Altar + Gemstone Array

Squee, the Immortal

Mana Echoes

Ashnod's Altar

Gemstone Array

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 Gemstone Array's first ability twice by paying 4, putting two charge counters on it.
5. Activate Gemstone Array's second ability twice by removing two charge counters from it, adding .
6. Repeat.
7. If you control four or more Goblins, this combo nets infinite mana.

This resilient engine turns Squee, the Immortal's unique ability to recast himself directly from the graveyard into an infinite loop of sacrifice and rebirth. Each time Squee re-enters the battlefield, Mana Echoes floods your pool with colorless mana thanks to the shared Goblin type, while Ashnod's Altar fuels the cycle by turning Squee's physical form into raw energy. Because you might need to filter your colorless energy into specific colors, Gemstone Array acts as the crucial conversion bridge, letting you store and trade those generic resources for any color you desire. Once you control four or more Goblins, the math tips in your favor to generate infinite mana of any color, infinite death triggers, and an unbounded storm count.
