Sasuke had an idea. He had Cynthia go on TV and make an announcement.

"Calling all powerful femal trainers," Cynthia said. "If you think you have what it takes to face me, I will be accepting challenges at my residence in the Sinnoh Pokemon League. No one will be turned away."

After the broadcast, as a precaution, Sasuke made a small wish to have all the powerful women trainers accept Cynthia's offer.

That would ensure Cynthia would be challenged by all the strong women in this world.
