Sister Hospitaller + Fiend Hunter + Carrion Feeder

Sister Hospitaller

Fiend Hunter

Carrion Feeder

How it works

1. Cast Fiend Hunter by paying its mana cost.
2. When Fiend Hunter enters, its first ability triggers, exiling Sister Hospitaller.
3. Activate Carrion Feeder by sacrificing Fiend Hunter.
4. When Fiend Hunter dies, its second ability triggers, returning Sister Hospitaller from exile to the battlefield.
5. When Sister Hospitaller enters, it triggers, returning Fiend Hunter from your graveyard to the battlefield.
6. When Fiend Hunter enters, its first ability triggers, exiling Sister Hospitaller.
7. Resolve the Carrion Feeder ability.
8. Repeat from step 3.

This clever loop relies on a continuous cycle of exile and resurrection to generate infinite value. You use Carrion Feeder as a reliable sacrifice outlet to send Fiend Hunter to the graveyard, which in turn triggers its own departure. That death allows the newly entering Sister Hospitaller to pull Fiend Hunter right back out of the graveyard and onto the battlefield, immediately exiling Sister Hospitaller all over again so the whole process can repeat.
