Earthen Ally [Avatar: The Last Airbender]

This creature gets +1/+0 for each color among Allies you control.

2WUBRG: Earthbend 5. (Target land you control becomes a 0/0 creature with haste that's still a land. Put five +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)
