Stomping Shores
Land (Rare)

Stomping Shores enters the battlefield tapped unless you pay R.

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

Tap: Add UR to your mana pool.

UR: Stomping Shores becomes a 2/1 red and blue Giant creature until end of turn. It's still a land.
