Ash's Gliscor

I knew that Ash has put all his Pokémon now in rotation, all of which he has kept at Professor Oak’s Laboratory and at Professors Kukui and Burnet’s home in the To Be a Pokémon Master sub-season. However, unfortunately, some of Ash’s Pokémon now in rotation that had not physically appeared in his sub-season include Noctowl, Torkoal, Gliscor, Gible, Lycanroc, Melmetal, Lucario and Dracovish. So, what if they all physically appeared in this sub-season? What do you think might happen? Please let me know, thanks.😉

Because Ash's Noctowl, Torkoal, Gliscor, Gible, Lycanroc, Melmetal and Lucario hadn't made their own physical appearance as in any of his To Be a Pokémon Master episodes, do you think that they'll physically make their own comeback as in his post-retirement anime work? Why?

All the Gliscor, including Ash's at Professor Oak's Laboratory, had appeared only in the Diamond and Pearl series. However, the only exception is that Ash's Gliscor is the only one of the Gliscor that had appeared only in the Japanese version of the Best Wishes series finale, "The Dream Continues", but only on the photo, along with Ash, Pikachu, his final Unova party and all their Pokémon at Professor Oak's Laboratory. So I wonder why you think that absolutely none of the Gliscor, including Ash's, have appeared in any of the other Pokémon anime series after the Best Wishes series?

All the wild and Trainer Gliscor, including Ash's, have appeared only in the Diamond and Pearl series from the Pokémon main anime. However, besides that Ash's Gliscor is the only one of them that appeared on a photo only in the original Japanese version of the Black and White series finale, "The Dream Continues", why do you think that none of the wild and Trainer Gliscor, including Ash's, have appeared in the XY and later series from the Pokémon main anime?
