Avatar Kyoshi, Earthbender

Legendary Creature — Human Avatar {5}{G}{G}{G} 6/6

During your turn, Avatar Kyoshi has hexproof. At the beginning of combat on your turn, earthbend 8, then untap that land. (Target land you control becomes a 0/0 creature with haste that's still a land. Put eight +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped.)
