Preston, the Vanisher + Wispweaver Angel + Karmic Guide

Preston, the Vanisher

Wispweaver Angel

Karmic Guide

How it works

1. Cast Karmic Guide by paying its mana cost.
2. When Karmic Guide enters, it triggers, returning Wispweaver Angel from your graveyard to the battlefield.
3. When Wispweaver Angel enters, it and Preston trigger.
4. Resolve the Wispweaver Angel trigger, blinking another permanent you control.
5. Resolve the Preston trigger, creating a token copy of Wispweaver Angel that is a 0/1 Illusion.
6. When the Wispweaver Angel token enters the battlefield, it triggers, blinking the nontoken Wispweaver Angel.
7. Repeat from step 3.
