Please rate my green and white MTG deck?

Unfortunately for this deck, most of the cards are pretty bad. The only cards I would consider keeping are the Shepherd of the Lost, the Sun Titan, and Llanowar Elves, the rest of the cards just arent good enough. You need 4 each of any card you play in a deck to increase the chances of drawing those cards to win you games. 1-2 of each card is not going to cut it. You need a couple more lands, 23 isnt enough.
