Breeding Watchtower
Land (Rare)

Whenever Breeding Watchtower becomes tapped, it deals 1 damage to you.

When Breeding Watchtower enters the battlefield, put a land you control on the bottom of its owner's library.

Tap: Add GW to your mana pool.

2G: Breeding Watchtower becomes a 2/2 green and white Leech creature with trample until end of turn. It's still a land.
