Salt Canopy
Land (Rare)

When Salt Canopy enters the battlefield, sacrifice it unless you pay G.

Tap: Add G or W to your mana pool.

Tap: Add 2 to your mana pool. Put Salt Canopy on top of your library.

GW: Salt Canopy becomes a 2/1 white and green Citizen creature until end of turn. It's still a land.
