lol even if its ridiculously hacked I haven't had a problem with local trades. Side note, I'm not exactly sure if PKHEX's legality checker has been updated, but even Pokemon I legitimately caught like Squirtle in the area North of Cerulean have shown as hacked/illegal in PKHEX. The day Nintendo requires online connectivity to verify before a local trade in combination with an actually strict legality checker is the day this has a chance of dying out.
