>>28153531I'd probably go the tryhard route at first, but then give up on being the Champ and focus on traveling the world.
Gallade would be my partnermon.
Metagross would be my main travelmon since that psychic floating is just so universally applicable.
Azumarill would be my goofy/cute-looking mon. I always liked her for being a fat rabbit that can hit like a truck, but all her buffs in Gen VI really made her shoot up my list of favorites.
Not sure about the other three, but I'd probably keep it that low just to make traveling and bonding easier. I'll probably end up using Alolan Marowak too if I could.
