Tropical Bluffs
Land (Rare)

Tropical Bluffs enters the battlefield tapped unless you sacrifice a multicolored permanent.

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

2: Tropical Bluffs becomes a 2/2 green Elf creature until end of turn. It's still a land.
