Aeve, Progenitor Ooze + Ashnod's Altar + Phyrexian Altar

Aeve, Progenitor Ooze

Ashnod's Altar

Phyrexian Altar

How it works

1. Cast Aeve from the command zone by paying 2 plus commander tax, if applicable.
2. Aeve's storm ability triggers, creating a nonlegendary token copy of itself for each spell you've cast previously this turn.
3. Activate Phyrexian Altar three times by sacrificing the nontoken Aeve and two Aeve tokens, adding .
4. Choose to have Aeve returned to the command zone from your graveyard.
5. Activate Ashnod's Altar by sacrificing an Aeve token, adding CC.
6. Repeat step 5 until you have enough mana to cast Aeve.
7. Repeat from step 1.

By leveraging the storm mechanic on Aeve, Progenitor Ooze, you can flood the board with nonlegendary token copies whenever you cast your commander, scaling off the spells you've already cast this turn. Once your army of Oozes is in place, you use Phyrexian Altar to generate the green mana needed to pay any accumulated commander tax while sending the original Aeve safely back to the command zone. Meanwhile, Ashnod's Altar converts the remaining token copies into a massive reserve of colorless mana to sustain the loop indefinitely. This creates a perpetual cycle of casting, sacrificing, and recasting that generates infinite storm count, death triggers, and colored or colorless mana.
