Earth Kingdom General - Avatar: The Last Airbender

When this creature enters, earthbend 2. (Target land you control becomes a 0/0 creature with haste that's still a land. Put two +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)

Whenever you put one or more +1/+1 counters on a creature, you may gain that much life. Do this only once each turn.
