My pokemon party(lvl 60)?

I'd say replace the lapras with something better. An unknown fact, is that ditto, trained correctly, can have the third highest stats in the game. Whip one of those out, and transform it into something big, and then kill your opponent with their own pokemon. Not only will it completely own, as it will be using it's stats, not the other pokemon, you have the possibility to be much stronger, at the same level.
