Forest Conclave
Land (Rare)

Forest Conclave enters the battlefield tapped unless you control four or more multicolored permanents.

Tap: Add G or U to your mana pool. Forest Conclave deals 1 damage to you.

2G: Forest Conclave becomes a 2/2 green and blue Leech creature with trample until end of turn. It's still a land.
