Seafloor Ravine
Land (Rare)

Seafloor Ravine enters the battlefield tapped.

When Seafloor Ravine enters the battlefield, put a land you control on the bottom of its owner's library.

Tap: Add UR to your mana pool.

3: Seafloor Ravine becomes a 2/2 blue Faerie creature until end of turn. It's still a land.
