Dualcaster Mage + Carrion Feeder + Graceful Reprieve

Dualcaster Mage

Carrion Feeder

Graceful Reprieve

How it works

1. Cast Graceful Reprieve by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Graceful Reprieve, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Graceful Reprieve.
5. Holding priority, activate Carrion Feeder by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, Graceful Reprieve triggers, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Carrion Feeder abilities from step 5.

This clever loop relies on the interaction between Graceful Reprieve and Dualcaster Mage to continuously retrigger its own entry effect while building an unstoppable board state. By having Dualcaster Mage copy the Reprieve to target itself, you set up an endless cycle where sacrificing the Mage to Carrion Feeder triggers the spell to bring the Mage right back to the battlefield. Meanwhile, Carrion Feeder acts as the ultimate outlet for this engine, turning the endless sacrifices into an infinitely large threat with a towering stack of +1/+1 counters.
