Lantern-Lit Grove
Land (Rare)

When Lantern-Lit Grove enters the battlefield, sacrifice it unless you pay 2 life.

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

2: Lantern-Lit Grove becomes a 2/2 green Leech creature until end of turn. It's still a land.
