Squee, the Immortal + Skyfire Phoenix + Cloud Key + Phyrexian Altar

Squee, the Immortal

Skyfire Phoenix

Cloud Key

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Squee and Skyfire Phoenix, adding .
2. Cast Squee from your graveyard by paying .
3. Skyfire Phoenix triggers, returning it from your graveyard to the battlefield.
4. Repeat.

This clever recursive loop turns your graveyard into an engine by letting Squee, the Immortal cast itself directly from exile or the graveyard repeatedly. Cloud Key acts as a vital cost reducer—naming "creature" so Squee can be cast for just a single red mana—while Phyrexian Altar provides the sacrifice outlet and generates the exact mana needed to recast him. Meanwhile, Skyfire Phoenix hitches a free ride straight back to the battlefield every time you cast your commander, allowing it to be sacrificed alongside Squee to continually fuel the altar's mana production.
