If this was the event deoxys that was caught with the aurora ticket, it would have the ID of the catcher. You can RNG your own ID in 3rd gen games where this was released. Kinda weird, I know.
You don't need to say sorry all the time xD I was wondering, though. When my shop's renovation is done, do you want to help me with Pokechecking all my pokemon to be sure of legitimacy? It would earn you a few pokemon over time
