The problem with the 1st team is that it has too many choiced mons that shouldn't be choiced! Serperior, Arcanine and Togekiss don't like to be locked into one move. I won't tell you to change any of your mons since you seem to work well with them, but you should totaly change their items and sets. I suggest SubSeed Serperior with lefties, Life Orb Arcanine with the same moves and Nasty Plot Toge with Thunder Wave
