SSBU/Mewtwo/Strategy

This is a whole can of worms i am NOT prepared to tackle, as Mewtwo is so versatile that nearly every Mewtwo player has their own distinct strategies they employ and Mewtwo can support a wide range of playstyles. However, I'll at least leave that every good Mewtwo heavily incorporates the many facets of Shadow Ball into their gameplan, wheter to help cover approaches, camp/zone, for movement, etc. It's such a versatile move in so many respects and should be used heavily by any M2 player, no matter what playstyle.
