Luminous Broodmoth + Pitiless Plunderer + Bloodsoaked Champion + Yahenni, Undying Partisan

Luminous Broodmoth

Pitiless Plunderer

Bloodsoaked Champion

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Bloodsoaked Champion.
2. When Bloodsoaked Champion dies, Luminous Broodmoth and Pitiless Plunderer trigger.
3. Resolve the Luminous Broodmoth trigger, returning Bloodsoaked Champion from your graveyard to the battlefield with a flying counter on it.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Activate Yahenni by sacrificing Bloodsoaked Champion.
6. When Bloodsoaked Champion dies, Pitiless Plunderer triggers, creating a Treasure token.
7. Resolve the Yahenni abilities from steps 1 and 5.
8. Activate the Treasures by tapping and sacrificing them, adding 1.
9. Activate Bloodsoaked Champion by paying 1, returning it from your graveyard to the battlefield.
10. Repeat.

This clever engine turns Yahenni, Undying Partisan into a relentless sacrifice outlet that funnels creatures straight to the graveyard while growing ever larger. Each time Bloodsoaked Champion meets its end, Luminous Broodmoth steps in to bring it right back thanks to its lack of flying, while Pitiless Plunderer simultaneously mints a Treasure token to fund the loop—or in subsequent iterations, pays the mana to recur Bloodsoaked Champion via its own raid ability.
