Pegasus Guardian // Rescue the Foal

How it works

2. Wispweaver Angel and Preston trigger.
3. Resolve the Wispweaver Angel trigger, blinking another creature you control.
4. Resolve the Preston trigger, creating a token copy of Wispweaver Angel that is a 0/1 Illusion.
5. When the Wispweaver Angel token enters the battlefield, it triggers, blinking the nontoken Wispweaver Angel.
