Dualcaster Mage + Self-Reflection

Dualcaster Mage

Self-Reflection

How it works

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

This brilliant loop starts by casting Self-Reflection to target a creature you control, setting the stage for Dualcaster Mage to jump in with flash and intercept the stack. When Dualcaster Mage enters the battlefield, its triggered ability targets the original Self-Reflection, creating a token copy of Dualcaster Mage itself. That brand-new token immediately triggers to copy Self-Reflection once more, perpetually chaining into an endless supply of creature tokens and entering-the-battlefield triggers.
