Copperline Store
Land (Rare)

Copperline Store enters the battlefield tapped unless you control two or more creatures.

Tap: Add G or W to your mana pool.

Put Copperline Store on top of your library: Add 1 to your mana pool.

1W: Copperline Store becomes a 0/4 green and white Bear creature with defender until end of turn. It's still a land.
