Watery Grove
Land (Rare)

When Watery Grove enters the battlefield, you lose 2 life unless you reveal an enchantment card from your hand.

Tap: Add GU to your mana pool. Watery Grove doesn't untap during your next untap step.

2: Watery Grove becomes a 2/2 blue Faerie creature until end of turn. It's still a land.
