Umbral Collar Zealot + Dualcaster Mage + Victimize

Umbral Collar Zealot

Dualcaster Mage

Victimize

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 Umbral Collar Zealot 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.

This clever loop hinges on Dualcaster Mage copying Victimize right off the stack, turning a single sorcery into a self-sustaining engine. Every iteration is fueled by sacrificing Dualcaster Mage to Umbral Collar Zealot, which conveniently dumps resources into your graveyard while enabling the sacrifice loop. Victimize then brings Dualcaster Mage right back alongside another creature, ready to target the original spell again and generate infinite deaths, enters-the-battlefield triggers, and surveils.
