Rate my MTG green/white deck?

Is this supposed to be... a casual deck to play just for fun. If it is, then it's fine I suppose. This deck looks like you threw together a bunch of cards you just had. It doesn't really make sense to me. Stick to a theme or idea. If you're gonna go life gain, then go life gain. The only thing I like here is the Leyline and Sword to Plowshares.
