Not sure if you are concrete about keeping each monster, but consider replacing Ariados with Heracross. I think Heracross will be a much stronger Bug presence for your team with the addition of Fighting coverage.

Also, a Sniper Kingdra becomes a beast if it knows Focus Energy. I would let go of its Flash Cannon and have the Move Reminder teach it Focus Energy.

Come to think of it, you may want to restructure Ninetales' moves. I find it very successful with Sunny Day, Flamethrower, Solarbeam and Confuse Ray.
