Where do you do use the Mystic Ticket in Pokemon Emerald?
Face every trainer in Hoenn 13 times.Then go up stairs in the
Pokemon center and there will be a man in a blue coat and a yellow
hat.Talk to the man and he wil ask you questions like "what is your
best Flying Pokemon"If the man says "you are a master of Pokemon,
wise you are"He will give you the mystic ticket.
