Coral-wood
Land (Rare)

Coral-wood enters the battlefield tapped unless you pay 1.

Tap: Add G or U to your mana pool.

Tap: Add 2 to your mana pool. Put Coral-wood on top of your library.

1U: Coral-wood becomes a 1/1 green and blue Cephalid creature with flying until end of turn. It's still a land.
