I completely agree, the fact that they all work together within themselves is really cool and it also allows normal Pokémon to have some of the spotlight too, as long as they don't take up and of the SIR slots, I really don't mindI still think they making the right decision. If you have a bunch of different trainers to complete a whole set the archetypes would be so weak and idk gameplay wise that doesnt seem fun. Or if you have few trainers but loads of pokemon for each thatd be interesting gameplay wise but you'd have a bunch of nonsensical pairings like idk Erika's Jigglypuff to say something. I dont mind if there's non canon pairings but if they do it in excess I do stop caring altogether
