Infuse with Vitality + Dualcaster Mage + Carrion Feeder

Infuse with Vitality

Dualcaster Mage

Carrion Feeder

How it works

1. Cast Infuse with Vitality by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Infuse with Vitality, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Infuse with Vitality.
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 sets up an infinite engine centered around Dualcaster Mage by granting it a recurring lease on life. By targeting the Mage with the copy of Infuse with Vitality created when it enters the battlefield, you ensure that whenever you sacrifice the Mage to Carrion Feeder, its delayed trigger immediately returns it to the battlefield to copy the spell all over again. As the cycle repeats, Carrion Feeder grows infinitely large with endless +1/+1 counters while you rack up unbounded life and death triggers.
