Haru, Hidden Talent (TLA 182)

Legendary Creature — Human Peasant Ally • Mana cost: {1}{G} • Avatar: The Last Airbender • Uncommon

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

Haru hid his incredible earthbending abilities out of fear of punishment from the Fire Nation.
