How it works

1. Cast Victimize by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Victimize.
4. Holding priority, activate Thermopod by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Victimize
6. Resolve the Victimize copy, sacrificing a creature and returning Dualcaster Mage and another creature from your graveyard to the battlefield.
7. Repeat from step 3.
