Stomping Steppe
Land (Rare)

When Stomping Steppe enters the battlefield, sacrifice it unless you pay 1 life.

Tap: Add R to your mana pool. If you played a land this turn, Add G to your mana pool instead.

1: Stomping Steppe becomes a 2/2 green Squirrel creature until end of turn. It's still a land.
