Garden of the Burnwillows
Land-Mountain Forest (Rare)

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

When Garden of the Burnwillows enters the battlefield, sacrifice it unless you pay G.

2G: Garden of the Burnwillows becomes a 2/2 red and green Elf creature with trample until end of turn. It's still a land.
