Preston, the Vanisher

Wormfang Drake

Yahenni, Undying Partisan

Nature's Rhythm

How it works

1. Cast Nature's Rhythm by paying at most 3, searching your library for Wormfang Drake and putting it onto the battlefield.
2. When Wormfang Drake enters, it and Preston trigger.
3. Resolve the Wormfang Drake trigger, exiling another creature if needed.
4. Resolve the Preston trigger, creating a token copy of Wormfang Drake that is a 0/1 Illusion.
5. When the Wormfang Drake token enters, it triggers, exiling the nontoken Wormfang Drake.
6. Activate Yahenni by sacrificing the Wormfang Drake token
7. When the Wormfang Drake token dies, it triggers, returning Wormfang Drake from exile to the battlefield.
8. Repeat from step 2.
