Rotlung Reanimator + Yahenni, Undying Partisan + Conspiracy

Rotlung Reanimator

Yahenni, Undying Partisan

Conspiracy

How it works

1. Activate Yahenni by sacrificing any other creature.
2. When the creature dies as a Cleric due to Conspiracy, Rotlung Reanimator triggers, creating a 2/2 Zombie creature token.
3. Resolve the Yahenni ability.
4. Repeat.

By naming "Cleric" as the chosen creature type for Conspiracy, every creature you own and control—including the tokens you are about to create—gains that classification. This turns Rotlung Reanimator into a relentless engine, converting each sacrifice into a fresh 2/2 Zombie creature token ready to be repurposed. You then feed those replacement bodies directly into Yahenni, Undying Partisan's activation cost, which simultaneously grows Yahenni's power with +1/+1 counters and fuels an endless loop of sacrifices, deaths, and arrivals.
