About Pokemon Recognized as Legal

Since this uses machine translation, there may be unintended errors.

Pokemon Bank is shutting down, so I plan to transfer my Pokémon to HOME, but I have a concern. If I transfer a Pokemon generated by PKHeX that has been verified as legitimate to HOME, is there a chance I could get banned?

Those Pokemon will be lacking a legitimate “Bank to HOME tracker”. PKHeX cannot create HOME trackers.

Currently there is a loophole where if the Pokemon enters via SWSH first, it will be able to enter HOME (HOME stops “transferred” monsters without a tracker from entering HOME, when deposited using other games).

however, they could close the loophole, and also retroactively ban/restrict mons that use the loophole.

An additional caveat for you to consider: just because PKHeX identifies something as "Legal" at this point in time does not mean it is 100% futureproof byte-for-byte equivalent to a legitimate Pokémon. I do not have a list of things that PKHeX does not currently check for. Improvements to checking & generating get added as the years go by, as we identify holes in the checks. So, previously "Legal" Pokémon become detectable as externally modified (e.g. not legitimate).

Generally, the official checks per-Pokémon are relatively weak and nowhere near as comprehensive as PKHeX, but again, no guarantees that this will always be the case. It wouldn't be hard for them to task an intern to bulk process an offline database of HOME using PKHeX's API to identify obvious cheaters who are originating the data, or they could task an AI agent to do so as well.

It is up to the end user to evaluate the risks of moving externally modified Pokémon through officially monitored systems like HOME. Players have been banned for obvious behaviors like account sharing, repeated trading of clones, and bulk moving of shared databases. They're usually narrowly targeted bans enacted by the developer. We've not seen the massive banwaves of pre-PKHeX-legality-checks in recent years, so maybe they've relented as PKHeX does a good job at dissuading impossible Pokémon.

I didn't explain that point clearly enough. After doing a final check in USUM, I plan to transfer my Pokémon from the “Bank” to ‘HOME’ following the official procedure. I had heard about the workaround that allows you to transfer Pokémon from “SWSH,” but I don't intend to use it.

So, if I want to be 100% sure, does that mean the best approach is to catch Pokémon in-game rather than using PKHeX to generate them? I should limit my use of PKHeX to indirect purposes, such as obtaining Mystery Gifts or acquiring items.

I found it useful to know that there haven’t been any large-scale crackdowns in recent years and that checks on individual Pokémon are relatively lax. I do have some Pokémon that were generated with PKHeX and then caught in-game and had ribbons and such applied to them, but I’ll consider starting over from scratch in-game.

Duh. To be 100% sure, you'd have to either encounter it without any cheats/shortcuts (e.g. legitimately) or fully understand what is entirely legal on a case-by-case basis, which requires a metric ton of legality/generating knowledge.

You're right. I'm sorry.
