Squee, the Immortal + Skyfire Phoenix + Runaway Steam-Kin + Thermopod

Squee, the Immortal

Skyfire Phoenix

Runaway Steam-Kin

Thermopod

How it works

1. If Runaway Steam-Kin has three or more +1/+1 counters on it, activate it by removing three +1/+1 counters from it, adding .
2. Activate Thermopod by sacrificing Squee and Skyfire Phoenix, adding .
3. Cast Squee from your graveyard by paying .
4. Skyfire Phoenix and Runaway Steam-Kin trigger.
5. Resolve the Skyfire Phoenix trigger, returning it from your graveyard to the battlefield.
6. Resolve the Runaway Steam-Kin trigger, putting a +1/+1 counter on it.
7. Repeat.

This loop turns your graveyard into an engine by weaponizing Squee, the Immortal's unique ability to be cast directly from exile or the graveyard alongside Skyfire Phoenix's triggered return whenever you cast your commander. By feeding these recursive threats to Thermopod, you generate the red mana needed to keep casting Squee over and over. Meanwhile, Runaway Steam-Kin acts as the critical battery that accumulates counters from your red spellcasting and converts them back into explosive bursts of mana, fueling the loop infinitely.
