Mortuary + Pitiless Plunderer + Yahenni, Undying Partisan + Eladamri, Korvecdal

Mortuary

Pitiless Plunderer

Yahenni, Undying Partisan

Eladamri, Korvecdal

How it works

1. Activate Yahenni by sacrificing the nontoken creature.
2. When the creature dies, Mortuary and Pitiless Plunderer trigger.
3. Resolve the Mortuary trigger, putting the creature from your graveyard onto the top of your library.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Resolve the Yahenni ability.
6. Activate the Treasure by tapping and sacrificing it, adding one mana of any color.
7. Cast the creature from the top of your library by paying its mana cost
8. Repeat.

This clever loop turns Yahenni, Undying Partisan into a self-sustaining engine by utilizing Mortuary to neatly recycle sacrificed creatures straight back to the top of your library. As those creatures perish, Pitiless Plunderer steps in to generate a steady stream of Treasure tokens that fuel the mana required to keep going. Meanwhile, Eladamri, Korvecdal lets you completely bypass the traditional drawing step, allowing you to seamlessly recast those recurring creatures straight off the top of your library over and over again.
