I wish they'd stop saying it's for battle balance, though. They really shouldn't hide behind that point when Noctowl is one of their confirmed picks. Sure, they did well splitting physical and special, splitting physical and special, and introducing Steel/Dark/Fairy Types, but when it comes to individual pokemon, they ain't too hot on this "competitive balance" idea. That said, since we don't know Sword and Shield's list, it could still wind up being 6 or 7 hundred pokemon long, just matters to me how the list is curated and what Pokemon Home does with the ones not included.
Spoiler: Personal snark that has been rolling around my head lately utilizing new pokemon stuffClearly, the reason why they needed to create Yamper's Ball Fetch ability is because they dropped the ball on making certain "everyone's here" after Smash Ultimate showed off how to do it.
