Cloudcrest Conclave
Land (Rare)

Cloudcrest Conclave enters the battlefield tapped unless you pay 1.

Tap: Add W or U to your mana pool.

Put Cloudcrest Conclave on top of your library: Add 1 to your mana pool.

2: Cloudcrest Conclave becomes a 2/2 blue Merfolk creature until end of turn. It's still a land.
