Dualcaster Mage + Undying Malice + Phantom Train

Dualcaster Mage

Undying Malice

Phantom Train

How it works

1. Cast Undying Malice by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Undying Malice, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Undying Malice.
5. Holding priority, activate Phantom Train by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Phantom Train abilities from step 5.

This clever loop sets up an infinitely repeating cycle of sacrifice and resurrection by turning Phantom Train into an active sacrifice outlet that feeds Dualcaster Mage right back into the battlefield. Every time Dualcaster Mage returns thanks to the lingering effect of Undying Malice, its entry trigger goes right back on the stack to copy another Undying Malice, ensuring the protection never wears off. Phantom Train not only facilitates this endless loop by turning away sacrifices for its own counter growth, but also cleanly converts your repetition into a staggering pile of persistent buffs.
