Attaboy Eoleo! Show him the wrath of the Champa pirates! ... Even if you are a Water type!
Well, our Smokescreens won't work if he's going to use Aerial Ace, but we can work around that. Stand your ground against the first Aerial Ace, and Yawn in his face. Then smack him with an Ice Punch after he tries to seed you. Finish the round by... Recovering :)
Yawn >>> Ice Punch >>> Recover
