Mega Mewtwo Y is a part of the Uber tier of competitive battling. With an enormous 194 base Special Attack and high base 140 Speed, Mega Mewtwo Y is a very potent offensive threat. With a great movepool that gives it optimal coverage, Mega Mewtwo Y can be very difficult to counter with its strong overall coverage. While usually a situational ability, Insomnia allows Mega Mewtwo Y to be immune to Darkrai's Dark Void and Smeargle's Spore. Mega Mewtwo Y can pull off a Calm Mind set more easily than normal Mewtwo due to its overall higher Speed and special bulk. Despite these traits, Mega Mewtwo Y is far from flawless, as it takes up a valuable Mega slot that can go to another Pokémon that offers greater defensive synergy or overall utility, like Mega Salamence or Mega Gengar. Mega Mewtwo Y also faces competition from normal base Mewtwo, which can still hold its own in terms of overall power and can take priority attacks like Rayquaza's Extreme Speed a lot better.
Mega Mewtwo Y was the first Mega Evolution to be revealed to the public.
