Breaking // Entering + Dualcaster Mage + Phantom Train

Breaking // Entering

Dualcaster Mage

Phantom Train

How it works

1. Cast Entering 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 Entering.
4. Holding priority, activate Phantom Train by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Entering, with the copy targeting Dualcaster Mage
6. Resolve the Entering copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop sets up an infinite recursion of graveyards and battlefields using the Entering half of Breaking // Entering to constantly reanimate your threats. The secret engine is Dualcaster Mage, whose entry trigger copies the very sorcery that brings it back, ensuring a never-ending chain of copies. To keep the loop going without running out of targets or space, Phantom Train acts as the necessary sacrifice outlet, allowing you to feed Dualcaster Mage to the Vehicle while simultaneously growing it with +1/+1 counters.
