This Set Is a sweeper set, but with a twist. It has 3 other uses. It can prevent your opponents Pokemon from setting up a sweep themselves, It can punish tanks,Phazers,etc from trying to stop your sweep, It can be used to spread status to your opponents Pokemon in general, while acting as a sweeper. Used this set in gen 3, and still use it now.
