Litten was my starter, and my main team is Incineroar, Hydreigon, Ampharos (mega), Gyarados, Rhyperior, and metagross. All my pokemon (pc included) all level 90 and over
I also completed sidequests (including Sandy’s sidequest. I don’t care if I lose relationship points for better reasons). Remember I caught every available Pokemons in this Reborn E18 and I got an Ultra Beast.
