Traveling Plague + Yahenni, Undying Partisan + Ghostly Dancers

Traveling Plague

Yahenni, Undying Partisan

Ghostly Dancers

How it works

1. Cast Traveling Plague by paying 3, attaching it to another creature you control.
2. When Traveling Plague enters, Ghostly Dancers triggers, creating a creature token.
3. Activate Yahenni by sacrificing the creature Traveling Plague is attached to.
4. When the creature dies, Traveling Plague triggers, returning itself from your graveyard to the battlefield attached to the token created in step 2.
5. When Traveling Plague enters, Ghostly Dancers triggers, creating a creature token.
6. Resolve the Yahenni ability.
7. Repeat from step 3.

This recursive loop uses Traveling Plague as a self-recycling engine that feeds on the creature it enchants. Whenever Yahenni, Undying Partisan sacrifices the enchanted creature, Traveling Plague's triggered ability capitalizes on that creature leaving the battlefield to return the Aura directly back to play, seamlessly attaching to a fresh target. That recurring entry is caught by Ghostly Dancers, whose eerie ability pumps out a fresh 3/1 white Spirit creature token each time to serve as the next vessel for the plague.
