Dualcaster Mage + Pegasus Guardian // Rescue the Foal

Dualcaster Mage

Pegasus Guardian // Rescue the Foal

How it works

1. Cast Pegasus Guardian // Rescue the Foal by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Pegasus Guardian // Rescue the Foal, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Pegasus Guardian // Rescue the Foal, blinking Dualcaster Mage.
5. Repeat from step 3.

This clever loop gets rolling when you cast Pegasus Guardian // Rescue the Foal as an adventure, with Dualcaster Mage waiting in the wings to intercept it on the stack. When Dualcaster Mage enters the battlefield, its triggered ability targets the adventure spell, creating a copy that resolves by exiling Dualcaster Mage and immediately returning it to the battlefield. This persistent blink creates an endless cycle of leaves-the-battlefield and enters-the-battlefield triggers, fueling infinite magecraft opportunities while Pegasus Guardian // Rescue the Foal safely waits in exile to be cast later.
