Dualcaster Mage + Supernatural Stamina + Phantom Train

Dualcaster Mage

Supernatural Stamina

Phantom Train

How it works

1. Cast Supernatural Stamina by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Supernatural Stamina, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Supernatural Stamina.
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 achieves infinite value by using Dualcaster Mage to continuously copy its own resurrection spell. As Dualcaster Mage enters the battlefield, its triggered ability targets Supernatural Stamina, ensuring a fresh copy is always ready to bring the wizard back when it hits the graveyard. Phantom Train provides the necessary outlet to sacrifice Dualcaster Mage on command while conveniently growing itself with +1/+1 counters each time. This creates a self-sustaining cycle of death and rebirth that triggers all your entering-the-battlefield, leaving-the-battlefield, and sacrifice effects indefinitely.
