Cloudcrest Wildwood
Land-Forest Plains (Rare)

(Tap: Add G or W to your mana pool.)

When Cloudcrest Wildwood enters the battlefield, you lose 1 life unless you reveal an artifact creature card from your hand.

1W: Cloudcrest Wildwood becomes a 0/4 green and white Knight Bird creature with defender until end of turn. It's still a land.
