How much are you missing? I'm not about to sit around trading 100 Pokémon, but I have every non-legendary Pokémon in my HOME 'dex bar Victreebel, Torterra, Wyrdeer, and Ursaluna (although don't have some of the the Gen V-VII that aren't available in SwSh / BDSP remaining)
I need like 7 for sword dex. Corsola and its evolution, Drampa I think its called, Zamazenta, lunatone, Oranguru and Aromatisse. Not looking for extended trade sessions, just someone who can form a mutual aide
