Olivia, Mobilized for War

Ashnod's Altar

Tresserhorn's Lord, Returned

How it works

1. Activate Ashnod's Altar by sacrificing the persist creature.
2. When the persist creature dies, it and Tresserhorn's Lord trigger.
3. Resolve the Tresserhorn's Lord trigger, causing you to draw a card.
4. Resolve the persist creature's trigger, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. When the persist creature enters the battlefield, Olivia triggers, putting a +1/+1 counter on the persist creature and causing you to discard a card.
6. Repeat.

This engine uses the recursion of a persist creature sacrificed to Ashnod's Altar to generate near-infinite colorless mana alongside endless death and enter-the-battlefield triggers. Tresserhorn's Lord, Returned serves as the crucial enabler, rewarding your sacrifices by letting you draw a card every time a creature hits the graveyard, turning the loop into a self-sustaining draw engine. Meanwhile, Olivia, Mobilized for War steps in whenever your persist creature returns, allowing you to cycle away unwanted cards and neutralize the creature's -1/-1 counter by placing a +1/+1 counter on it, which ensures the loop can continue indefinitely.
