Verdant Shrine
Land (Rare)

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

Tap: Add G to your mana pool. If you played a land this turn, Add W to your mana pool instead.

3: Verdant Shrine becomes a 2/2 white Cleric creature until end of turn. It's still a land.
