Preston, the Vanisher

Wispweaver Angel

Chord of Calling

How it works

1. Cast Chord of Calling by paying at most 6, searching your library for Wispweaver Angel and putting it onto the battlefield.
2. When Wispweaver Angel enters, Wispweaver Angel and Preston trigger.
3. Resolve the Wispweaver Angel trigger, blinking another permanent 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.
6. Repeat from step 2.
