>>31742607It was kind of cute in VGC 2016, because Mega Mewtwo X would use a STAB rain boosted Water Spout or Precipes Blades against the Kyogre/Groundon that launched it before they used their's.
Unfortunately, that was all it could to and Mewtwo was really bad in VGC 2016. Special didn't hit hard enough to be relevant (I know, right?) and if it mega evolved into X, Mewtwo got bumfucked by Talonflame and the stupid elk..
