How it works
Cast Victimize by paying its mana cost
Holding priority, cast Dualcaster Mage by paying its mana cost.
When Dualcaster Mage enters, it triggers, targeting Victimize.
Holding priority, activate Phantom Train by sacrificing Dualcaster Mage.
Resolve the Dualcaster Mage trigger, copying Victimize
Resolve the Victimize copy, sacrificing a creature and returning Dualcaster Mage and another creature from your graveyard to the battlefield.
Repeat from step 3.
This clever loop uses Phantom Train's sacrifice ability as an engine to continuously feed your graveyard, turning Dualcaster Mage and Victimize into a self-sustaining cycle. When you cast Victimize and flash in Dualcaster Mage, the Mage's entry trigger copies the spell to reanimate both the Mage and another creature from your graveyard. Before that copy resolves, you can sacrifice the Dualcaster Mage to Phantom Train—growing the Train and putting the Mage right back into the graveyard so Victimize's copy can pull it back out again alongside whatever else you need.
