Mikaeus, the Unhallowed + Luminous Broodmoth + Carrion Feeder

Mikaeus, the Unhallowed

Luminous Broodmoth

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing it.
2. When Carrion Feeder dies, its undying ability triggers if it didn't have a +1/+1 counter, and Luminous Broodmoth triggers if Carrion Feeder didn't have flying.
3. Resolve the undying trigger, if applicable, returning Carrion Feeder from your graveyard to the battlefield with a +1/+1 counter on it.
4. Resolve the Luminous Broodmoth trigger, if applicable, returning Carrion Feeder from your graveyard to the battlefield with a flying counter on it if Carrion Feeder is still in your graveyard.
5. Resolve the Carrion Feeder ability.
6. Repeat.
