Enduring Renewal + Ashnod's Altar + Phyrexian Altar + Liberated Livestock

Enduring Renewal

Ashnod's Altar

Phyrexian Altar

Liberated Livestock

How it works

1. Activate Phyrexian Altar by sacrificing Liberated Livestock, adding .
2. When Liberated Livestock dies, it and Enduring Renewal trigger.
3. Resolve the Liberated Livestock trigger, creating a 1/1 Cat, a 1/1 Bird, and a 2/4 Ox creature token.
4. Resolve the Enduring Renewal trigger, returning Liberated Livestock to your hand from your graveyard.
5. Activate Ashnod's Altar three times by sacrificing the Bird, Cat and Ox, adding six C.
6. Cast Liberated Livestock by paying 5.
7. Repeat.
8. Once you have infinite colorless mana, you may forego sacrificing tokens to Ashnod's Altar.

This brilliant loop turns the multi-token generation of Liberated Livestock into a self-sustaining engine, kept alive by Enduring Renewal's passive ability to constantly scoop the card right back to your hand whenever it dies. As you cycle the livestock through sacrifice, Ashnod's Altar and Phyrexian Altar work in tandem to convert your sacrificial offerings and the resulting token swarm into a net surplus of both colored and colorless mana. Because Enduring Renewal ensures you never actually have to spend cards from your hand permanently, you can recast the livestock endlessly while piling up an astronomical storm count and an infinite army of tokens.
