Twilight Hollows
Land (Rare)

Twilight Hollows enters the battlefield tapped unless you reveal a Treefolk card from your hand.

B, Tap: Add GG to your mana pool.

G, Tap: Add BB to your mana pool.

2G: Twilight Hollows becomes a 2/2 black and green Horror Rat creature with trample until end of turn. It's still a land.
