I'm not exactly an expert here but you could probably get rid of a few energys there since both main attacks cost 1{P} which is mews thing and 1{G} for mass attack. So maybe something like...
-2 psy
-2 grass
I would probably wait until someone more qualifyed be the judge though. Also you...
After seeing the kyurem card its obviously going to be a top tier card in my opinion so as far as making a deck around it I was thinking something like.
4 Kyurem
2-2-2 Ferilgtor Prime
3-3-3 Kingdra prime

Taking all that into account...
