Pokemon might never be on TV again.
The Aurora Ticket is obtainable though events which, unfortunatly, are no longer running. It is impossible to get the Aurora Ticket now, since they will never run the event again, and the Aurora Ticket cannot be traded from one game to another. If you want the Pokemon which the Aurora ticket allows you to capture, you'll have to trade with someone else to get it.
