Mistveil Sandstone
Land-Mountain Plains (Rare)

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

Mistveil Sandstone enters the battlefield tapped unless you pay 1 life.

WW: Prevent the next 1 damage that would be dealt to target creature or player this turn.

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