Rate/Fix my Crystal Beast deck (yugioh)?

Hey, it is a pretty nice deck. It is well tought out and looks like it could cause some trouble!!! I would maybe advise you to take out the second rainbow dragon just, because their are very hard to summon. Try to add some more magic cards like heavy storm and Mystical space typhoon, and magic cards that support your monsters. You can try adding a morphing jar, because it can dump your crystal beats into the grave so you can summon rainbow dragon faster. Lastly, I would try to get some new crystal beast support cards from the new Jesse Anderson pack, like Crystal Realease, Rare Value, and Crystal Tree. They are hard to get, but will make a great addition to your already good crystal beast deck. If you have a local card shop you can get some good deals there. Hope these changes will make your crystal beast deck even beaster!!!
