Mikaeus, the Unhallowed + Luminous Broodmoth + Bloodflow Connoisseur

Mikaeus, the Unhallowed

Luminous Broodmoth

Bloodflow Connoisseur

How it works

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