Do you mean like the way we say " Hey, remember that league where Ash lost to a Meowth dressed as a fairytale character? Haha"I mean when we look back at this league years from now, are we going to say, "Hey remember that league when Ash lost to a Leafeon as his final opponent? Haha."
This one will be more along the lines of " Hey remember that league where Ash lost to an Eevee as his final opponent?" But instead of saying haha we'll just get depressed, even though the majority of fans predicted that outcome.
With the revelation that Kotetsu has a freaking Hydreigon (nice curve ball writers), it is possible that Ash loses to him. Although he has several pokemon that can beat it, mainly Krookodile, and we've seen Pikachu take down strong pokes time and time again. But im picking ash to win, because I think the Kotetsu battle will be a 3 v 3 (educated guess), which would still leave Unova pokes not getting a battle yet, so they can début against Virgil. Ash then loses to Eevee, giving him a top 16 spot, provided they don't have rushed battles against Cotd's, and I would be pleased with a top 16 spot looking at Ash's team
