My team at the moment is Greninja, Arcanine, Magnezone, Noivern, Gothitelle, Golem. I reached Luna and lost pretty easily. My team is around levels 56 and her team around 64 so I decided to level up a bit before try again, the thing is since i'm going to do some grinding I decided to get new members on the team, I got a Ralts and a Swinub now and replace Golem and Gothitelle. Golem was good but is turning a bit useless now and Gothitelle is really good but I kinda need a fairy type.
Now the thing is i've Kirlia at 22, Swinub at 28 and the rest of the team at 56. Where is a good place to level up? Some talk about the Unow at Arceus door but it may be outdated information.
edited: Btw what you think about changing Noivern for a Crobat? I really like both pokemon but probably crobat is better typing.
