4. Resolve the Athreos trigger, returning the creature from your graveyard to the battlefield.
5. Resolve the Bloodthrone Vampire ability from step 1.
6. Activate Bloodthrone Vampire by sacrificing Resourceful Defense.
7. When Resourceful Defense dies, it and Athreos's second ability trigger.
8. Resolve the Resourceful Defense trigger, putting a coin counter and +1/+1 counters onto the other nontoken creature.
9. Resolve the Athreos trigger, returning Resourceful Defense from your graveyard to the battlefield.
10. Resolve the Bloodthrone Vampire ability from step 6.
11. Repeat.
