Well, I'm at Aether Paradise right now, getting ready to save Lillie and Nebby.  Team is as follows

Ash the Movie Hat Pikachu (Not actually nicknamed, since it's not owned by me)
Boombox the Noibat
Azula the Alolan Marowak
Fenrir the Dusk Lycanroc
Ariel the Primarina
Ursula the Malamar

Although Boombox is one level away from becoming Noivern, and I'm thinking about switching out Pikachu for a Mareep, who become an Ampharos, named Wattson.
