The thing that surprises me most about the treatment of his Journeys team is that you’d expect this cast of fan favorite Pokémon to be in nearly every episode but they easily have the least amount of collective screentime for any team even if you look for the first ~90 episodes of others series since Journeys isn’t over yet.
Another thing that helped with his starters is that they were caught unevolved and the ones who were the “aces” like Charizard, Sceptile, Infernape, & Greninja had a lot of their development tied to each of their evolutionary stages. Out of his 5 Pokémon for this series, 2 were caught fully evolved and 1 can’t evolve. I don’t think it’s a coincidence that Lucario & Sirfetch’d got the most relatively consistent development since they had time to work on something which is easier to show through their pre evolved forms. Even with his old teams, Pokémon that couldn’t/didn’t evolve like Noctowl, Corphish, Torkoal, Palpitoad, & Hawlucha got little to no development outside of their debut episodes. Some of them made up for it with their personalities and/or battle skill but a lot just kind of phased into the background. I’m not saying him catching a Dratini, Gastly, and any combination of the Galar starters would’ve suddenly given his team significantly more screentime but it definitely would’ve helped.
