This land enters tapped. {T}: Add {G}. {1}{G}: This land becomes a 3/3 green Ape creature with trample until end of turn. It's still a land. (It can deal excess combat damage to the player or planeswalker it's attacking.)

Whenever another creature you control enters, you may gain 1 life. Whenever a creature an opponent controls enters, you may have that player lose 1 life.

When this creature enters, each opponent may put any number of artifact, creature, enchantment, and/or land cards from their hand onto the battlefield.
