A bit of a stretch for a joke, yeah, but I like to think that even people who don't do competitive Pokemon could get this. If you don't, in X and Y Talonflame was the most used Pokemon in the Over Used meta, but Sun and Moon nerfed his Gale Wings ability so bad that they've dropped to the Rarely Used tier. Gengar's ability change might be bad, but as least they're still competitively viable...I think. I'm surprised I haven't seen more jokes about this.
Pokemon belongs to Nintendo, Game Freak, and the Pkmn company...you know, this joke would have been better if I made it about three months ago...
