Toph, Earthbending Master (TLE-145) [Avatar: The Last Airbender: Eternal-Legal] Foil

Landfall — Whenever a land you control enters, you get an experience counter.

Whenever you attack, earthbend X, where X is the number of experience counters you have. (Target land you control becomes a 0/0 creature with haste that's still a land. Put X + 1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)
