Dualcaster Mage + Electroduplicate

Dualcaster Mage

Electroduplicate

How it works

1. Cast Electroduplicate by paying its mana cost, targeting a creature you control.
2. Holding priority, cast Dualcaster Mage by paying 1.
3. When Dualcaster Mage enters the battlefield, it triggers, copying Electroduplicate, targeting Dualcaster Mage.
4. Resolve the copy of Electroduplicate, creating a token copy of Dualcaster Mage.
5. Repeat from step 3.

This clever loop begins the moment you cast Electroduplicate targeting any creature you control, setting the stage before you hold priority to slide in Dualcaster Mage with flash. As Dualcaster Mage enters the battlefield, its trigger zeroes in on the original Electroduplicate, creating a token copy of Dualcaster Mage that instantly triggers anew to copy the spell again. Because Electroduplicate's copy can keep targeting the newly manifested token copies of Dualcaster Mage, you generate an endless cascade of haste-imbued duplicates that feed your death, sacrifice, and magecraft triggers indefinitely.
