I agree with
>>43497334 in the first two gyms
Change Whitney's Clefairy because Fairy exist (GSC sprites just because they are the peak of sprites)
I desagree with
>>43497406 and
>>43497468 (valid arguments, but not to a very limited region like Johto - my favorite, but that's truth) so I put some of the Alolan and Galarian Forms in. The same with evolutions.
Morty have a thing with tradition and past, so I bring Corsola (here, an allusion to lost tradition). Mismagius just because we needed.
Can we get a Johtonian Haryiama?
Jasmine always have the "cute but tough" aura. Perrserker seems to fit (and I love this goofy thing).
Pryce seems prideful in that original sprite, and fit with Alolan Ninetales.
Clair is a tough team to make. I don't see her with Alolan Exeggutor (or Lance), so I bring some strong feminine Pokémon and some of associated with Dragons.
In E4, some of the Pokémon chosen aren't the type of the specialist, but a great coverage.
I support the theory that Will and Lorelei are the same person... So I put half of Lorelei team's here.
Lance (almost) isn't a Flying-type user anymore!
