Boiler-Village
Land (Rare)

Boiler-Village enters the battlefield tapped unless you sacrifice a colorless permanent.

Tap: Add R or G to your mana pool.

Put Boiler-Village on top of your library: Add 1 to your mana pool.

RG: Boiler-Village becomes a 2/1 red and green Beast Elemental creature until end of turn. It's still a land.
