And with Pokemon Z-A we're likely to see the same thing again, with ancestors of various Kalos characters using the same Pokemon as the present-day descendants, as if they get passed down the way real players once wanted to. It's a very strange creative choice if Dexit is truly the new norm.

Despite people's claims that delaying the games would fuck up everything else, most of the franchise continued like Dexit never happened, from the anime to spinoff games. Including the TCG, Creatures prints whatever mons they want, even if they're not available in the corresponding video game.
