To note, Psywave was never "officially" banned, as I found out from investigating things with Hogg. It's a long story, but regardless, it shouldn't be there.
Japan-exclusive moves don't necessarily need to be claused out, as they simply don't exist in the international games. It's better to just add a note saying "Yeah these aren't obtainable gottem ggs". If you do try to trade, you just corrupt your save file.
Also a list of mons with the issue for those looking to add notes, all but Phanpy are RBY only.
- Pay Day Rapidash
- Pay Day Fearow
- Fly Pikachu
- Dragon Rage Magikarp
- Encore Phanpy + Donphan
