Activate Viscera Seer 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 Viscera Seer ability, causing you to scry 1.
Repeat.
This clever recursive loop turns your graveyard into a revolving door by leveraging the delayed-trigger safety net of Athreos, Shroud-Veiled to continuously yank a coin-countered creature right back to the battlefield. Whenever that creature hits the graveyard, Reluctant Role Model's triggered ability steps in to ensure the coin counter (or whatever other counters it carried) safely transfers to another target creature you control, preserving your setup for the next iteration. Meanwhile, Viscera Seer acts as the reliable sacrifice engine that kicks off the entire sequence at instant speed while letting you scry away unwanted draws.
