Create a Food token. Then earthbend X, where X is twice the number of Foods you control. (A Food token is an artifact with "2, T, Sacrifice this token: You gain 3 life." To earthbend X, 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.)
