Mistveil Bridge
Land (Rare)

At the beginning of your end step, if you didn't cast any spells this turn, Mistveil Bridge deals 1 damage to you.

Tap: Add G or W to your mana pool. Mistveil Bridge deals 2 damage to you.

GW: Mistveil Bridge becomes a 2/1 white and green Kor creature until end of turn. It's still a land.
