Pikasaur
Lazy Summer
I'd love if his team line up was Pikachu, Torracat (because Incineroar), Sceptile, Heracross, Greninja, Krookodile etc etc but I'm pretty sure he's gonna stick with the team he had now to see him through.
Plus Melmetal needs a win
It would be interesting for his Classmates to see the Geninja-Bond thing, Ash can do.
there is no way for him to get Greninja between Guzzlord Returning and the Kukui fight though
