Athreos, Shroud-Veiled + Bloodflow Connoisseur + Reluctant Role Model

Athreos, Shroud-Veiled

Bloodflow Connoisseur

Reluctant Role Model

How it works

1. Activate Bloodflow Connoisseur by sacrificing the creature with a coin counter on it.
2. When the creature dies, Athreos's second ability and Reluctant Role Model's second ability trigger.
3. Resolve the Athreos trigger, returning the creature from your graveyard to the battlefield.
4. Resolve the Reluctant Role Model trigger, putting a coin counter on it if it wasn't the creature that was sacrificed, or another nontoken creature you control otherwise.
5. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Repeat.
