>>53956738Its stats look like this.
In SV, it's the second fastest Pokemon, only behind Regieleki and tied with Electrode.
It also has a better SpA than Mewtwo with an additional STAB.
Its defenses, while not great, are also not debilitatingly terrible.
It has a 120 BP Ghost-type move with no downsides.
It has access to Psyshock, which can fuck over any special walls.
It has access to Nasty Plot, just in case it was ever faced with anything that it couldn't melt instantly.
The only real weakness it had and only reason it wasn't banned last gen is that it has a 4x weakness to Dark, and the strongest priority move in the game was Yveltal's Sucker Punch. Yveltal had 90+% usage last gen for this reason.
Now Yveltal is gone and even if it wasn't Spectrier can just tera into something that resists Dark.
