Athreos, Shroud-Veiled + Enduring Bondwarden + Carrion Feeder

Athreos, Shroud-Veiled

Enduring Bondwarden

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Enduring Bondwarden.
2. When Enduring Bondwarden dies, it and Athreos' third ability trigger.
3. Resolve the Enduring Bondwarden trigger, putting all counters from it onto another nontoken creature you control.
4. Resolve the Athreos trigger, returning Enduring Bondwarden from your graveyard to the battlefield.
5. When Enduring Bondwarden enters the battlefield, its backup ability triggers, putting a +1/+1 counter on the creature who had a coin counter placed on it, and giving it the printed ability until end of turn.
6. Resolve the Carrion Feeder ability from step 1, putting a +1/+1 counter on it.
7. Activate Carrion Feeder by sacrificing the nontoken creature with a coin counter on it.
8. When the creature dies, it and Athreos' third ability trigger.
9. Resolve the creature's trigger, putting all counters from it onto Enduring Bondwarden .
10. Resolve the Athreos trigger, returning the creature from your graveyard to the battlefield.
11. Resolve the Carrion Feeder ability from step 7, putting a +1/+1 counter on it.
12. Repeat.

This clever loop transforms Athreos, Shroud-Veiled into an eternal reclamation engine by leveraging its ability to continuously return coin-marked creatures to the battlefield. Carrion Feeder serves as the necessary sacrifice outlet to send your targets to the graveyard, while Enduring Bondwarden acts as the catalyst that lets your creatures endlessly accumulate and bounce their counters back and forth. Because every iteration triggers the Bondwarden's death ability and the Athreos return clause, you can infinitely recycle your creatures to pump up your board with boundless power.
