Yeah I'm loving Munna. Her Nature isn't too helpful but I like using her, also because generally manga chars don't use Psychic Pokemon so it's nice to have one for now. I think her current moveset is Psybeam, Moonlight, Lucky Chant and Yawn. Imprison was nice but Munna has a pretty special moveset I thought, and hey heal.
Beat the second gym, all Arm Thrust and Flame Charge aww yeah.
