AR Pokemon Black and White Help

[Sync]

Hi, I apologize if the answer to this question is glaringly obvious, but I have not been able to find it.

If you use an AR to change the nickname of a traded Pokemon, does that Pokemon become illegal in tournaments? Or does the Pokemon stay legal? Meaning, will the Pokemon appear hacked.

Also, I was once told that clones are scanned as hacked unless they are traded to a different game. So, say, if someone cloned a Vulpix in their game, it would come up as hacked. However, if they traded that Pokemon to a different game, it would not be hacked. Is that true?

Thank you for any help.

Everyone should think that it was originally nicknamed that unless it is an event.

(Probably should have gone in the pkm legality forum)

Thank you.
