Rootpath Purifier

Wheel of Sun and Moon

Fabled Passage

How it works

1. Activate Fabled Passage by tapping and sacrificing it.
2. Fabled Passage is put on the bottom of your library instead of in your graveyard due to Wheel of Sun and Moon.
3. Resolve the Fabled Passage ability, searching your library for Fabled Passage and putting it onto the battlefield.
4. Repeat.
