Grass-Everglades
Land (Rare)

Whenever Grass-Everglades becomes tapped, it deals 1 damage to you.

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

2G: Grass-Everglades becomes a 2/2 black and green Leech creature with trample until end of turn. It's still a land.
