I don’t mind if he evolves his Pokémon, I just want some of them to not fully evolve because I would like to see some of Ash’s Pokémon be used again. So Pokémon like Grimer, Talliow, and his future Fletchling to not evolve so that Muk, Swellow, and Talonflame can be used again.
All of them are good choices, I would like to see Kingler, Noivern since he didn’t get to do much during Kalos, Sceptile, Staraptor, Muk, Swellow, Talonflame, Donphan, Quilava to come back and evolve to Typhlosion, Totodile to evolve all the way, Snorlax, Squirtle, Bulbasaur and Heracross since it’s my favorite bug Pokémon. Also the Pokémon that you mentioned.
