Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Ashnod's Altar + Peema Outrider

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

Ashnod's Altar

Peema Outrider

How it works

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

This clever loop transforms Ashnod's Altar and Peema Outrider into a relentless engine of sacrifice, supercharged by the unique tools found on Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight. While Ashnod's Altar provides the colorless mana and a way to send Peema Outrider to the graveyard, Isilu's passive static ability grants Peema Outrider the persist keyword it needs to return from the dead with a -1/-1 counter. As soon as Peema Outrider re-enters the battlefield, its fabricate ability triggers to place a +1/+1 counter on it, which immediately neutralizes the existing -1/-1 counter through state-based actions and sets you up to repeat the entire cycle for infinite colorless mana, leaves-the-battlefield triggers, and death triggers.
