would appreciate a team review, rate mine please thanks all

[Dreathor]

ok this was my team this morning, but i also just finished the wii battle revolution game and got the three pokemon from it, and finished ev training a vaporeon, ive got both games so can get practically anything so any suggestions are awsome. won most wifi games so far except when i was fighting against Rayquaza, that kicked my team down fast, but i think I need some anti-dragon moves somewhere and maybe rain dance in the team, thats my main focus but maybe you see other weaknesses somewhere, thanks!
