According to someone who has seen Pokemon Fan magazine, which is officially released tomorrow, Ash uses the same team as his last battle with Paul (including Gliscor), and Paul uses a drastically different team.
Ash - Pikachu, Infernape, Torterra, Staraptor, Buizel, Gliscor
Paul - Electivire, Ninjask, Aggron, Drapion, Froslass, Gastrodon(East)
Thats the biggest twist ever. Even bigger than Gliscor reappearing for the battle. Paul is removing Magmortar, Torterra and most of all Honchkrow from the battle? Thats totally weird cause I was hoping that Ash's Torterra will redeem itself before being Oaked but it can't if it beats something like Gastrodon. For the first time, I want Slowkingsley news is wrong. I have waited so long to watch how Torterra will crush the bossy raven and now they throw this at us.
