…Sure? It’s not that hard at all? It’s like 5 minutes of low effort Pokemon moving if you’ve built up a living dex. You can just pick up the first 488 in home, plop em down, save in game, and move them back. I don’t see why you seem to think the actual effort behind moving all those Pokémon is anything troublesome. Like, getting the actual living dex isn’t the easiest but that’s a different conversation. It’s only like a trade evolution’s worth of taking time to do something if you have all the Pokémon on hand already. In exchange, the underground suddenly goes to having wild area tier Pokémon diversity. Sounds like an interesting way to mix up future playthroughs if I’ve ever heard one.
