Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Phyrexian Altar

Ambitious Aetherborn

How it works

1. Activate Phyrexian Altar by sacrificing Ambitious Aetherborn.
2. When Ambitious Aetherborn dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Ambitious Aetherborn enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Repeat.

This brilliant loop hinges on the unique alchemy of Eirdu, Carrier of Dawn granting persist to your other nontoken creatures, allowing Ambitious Aetherborn to continuously cheat death by trading its impending doom for a -1/+1 counter cancellation. Whenever Ambitious Aetherborn returns to the battlefield, its fabricate ability triggers to place a +1/+1 counter upon it, which immediately neutralizes the persist-derived -1/-1 counter so the cycle can begin anew. Meanwhile, Phyrexian Altar acts as the sacrificial engine that converts this endless resurrection loop into an infinite supply of colored mana, fully supported by Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight's front face giving your creature spells convoke to help recast your pieces if needed.
