Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Morselhoarder + Bartolomé del Presidio

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

Morselhoarder

Bartolomé del Presidio

How it works

1. If Morselhoarder has any -1/-1 counters on it, activate it by removing a -1/-1 counter from it, adding one mana of any color.
2. Repeat step 1 as necessary until Morselhoarder has no -1/-1 counters on it.
3. Activate Bartolomé del Presidio by sacrificing Morselhoarder.
4. When Morselhoarder dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. Resolve the Bartolomé del Presidio ability.
6. Repeat.

This elegant loop transforms the back face of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight into a persistent engine by granting Morselhoarder the persist ability as a nontoken creature. As you filter away Morselhoarder's natural -1/-1 counters for colored mana, you can finally sacrifice it to Bartolomé del Presidio, triggering its return to the battlefield with a single fresh -1/-1 counter. Because Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight ensures it keeps coming back, you can endlessly repeat the sacrifice to grow Bartolomé del Presidio into a massive threat while generating infinite mana and death triggers.
