The token spam element in here could help

Green, if you put a flamekin harbinger in the deck and got it out, you could have more creatures swinging fast and hard. The big plus for this is getting cheap cards out very fast, and it works well early on for control.
I think that the Whip of Erebos would be pretty good if you're gonna have creatures that are only out for a little bit. Pay four and you get them back for a while, them hit hard and throw 'em away. You're in the same place as before, but you did more damage. Also, are token decks a problem for you?
