Umbral Collar Zealot + Dualcaster Mage + Persist

Umbral Collar Zealot

Dualcaster Mage

Persist

How it works

1. Cast Persist by paying its mana cost, targeting any applicable target.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Persist.
4. Holding priority, activate Umbral Collar Zealot by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Persist, with the copy targeting Dualcaster Mage
6. Resolve the Persist copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop turns a simple recursion spell into an infinite engine by pairing Persist with Dualcaster Mage to continuously bring the Mage back from the graveyard. To keep the loop going indefinitely without filling up your hand or board, Umbral Collar Zealot steps in as the ultimate sacrifice outlet, letting you pitch the Mage and sculpt your draws with infinite surveil triggers along the way. Every time Dualcaster Mage enters the battlefield, it copies the original Persist to target itself anew, generating an endless cascade of enters-the-battlefield, leaves-the-battlefield, and death triggers.
