Well right now your deck seems a little low on creatures and Kor Spiritdancer would be a perfect addition. Also, as of right now you don't have any cards that cost more than two mana, so adding, say, two Spheres of Safety shouldn't be too much of a problem.
Also, if you're worried about your Kor Spiritdancers being taken out easily because they don't have Hexproof, I suggest adding this card:
Privileged Position (Mana Cost: 2 Colorless, 3 G/W)
(G/W can be paid with either Green or White Mana)
Other permanents you control can't be the targets of spells or abilities your opponents control.
Essentially it gives all of your other permanents Hexproof. The card itself doesn't have Hexproof unless you have a second Privileged Position on the battlefield.
