Dualcaster Mage + Carrion Feeder + Undying Malice

Dualcaster Mage

Carrion Feeder

Undying Malice

How it works

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

This clever loop turns a simple spell and a flash wizard into an infinite engine, powered entirely by Dualcaster Mage entering the battlefield to copy its own resurrection magic. By holding priority and sacrificing the Mage to Carrion Feeder, you trigger the undying effect granted by Undying Malice, bringing the Mage right back to the battlefield to repeat the process. This endless cycle not only pumps Carrion Feeder full of infinite +1/+1 counters through endless sacrifices, but also triggers any number of enter-the-battlefield, leaves-the-battlefield, and death events.
