There is a coin counter on any creature you control except
Athreos.
You control at least one additional nontoken creature if
Reluctant Role Model is the only creature you control with a coin counter on it.
Steps
Activate
Bartolomé del Presidio by sacrificing the creature with a coin counter on it.
When the creature dies,
Athreos's second ability and
Reluctant Role Model's second ability trigger.
Resolve the
Athreos trigger, returning the creature from your graveyard to the battlefield.
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.
Resolve the
Bartolomé del Presidio ability, putting a +1/+1 counter on it.
