Dualcaster Mage + Cackling Counterpart

Dualcaster Mage

Cackling Counterpart

How it works

1. Cast Cackling Counterpart 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 Cackling Counterpart, targeting Dualcaster Mage.
4. Resolve the copy of Cackling Counterpart, creating a token copy of Dualcaster Mage.
5. Repeat from step 3.

This clever loop starts by casting Cackling Counterpart to target an existing creature, setting the stage for Dualcaster Mage to enter with flash and intercept the spell on the stack. When Dualcaster Mage's triggered ability copies Cackling Counterpart to target the Mage itself, it creates a fresh token copy that perpetually repeats the process. This self-sustaining cycle floods the battlefield with an endless army of spell-copying wizards, generating infinite enters-the-battlefield triggers and magecraft opportunities entirely at instant speed.
