Unstable Thicket
Land-Mountain Forest (Rare)

(Tap: Add R or G to your mana pool.)

Unstable Thicket enters the battlefield tapped unless you reveal an artifact land card from your hand.

2G: Unstable Thicket becomes a 2/2 red and green Elemental creature with trample until end of turn. It's still a land.
