Arid Karst
Land-Forest Plains (Rare)

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

When Arid Karst enters the battlefield, return a land you control to its owner's hand.

WW: Prevent the next 2 damage that would be dealt to target creature or player this turn.

2, Tap: Target land becomes a 3/3 green Elf creature until end of turn. It's still a land.
