Of course she looks majestic, why do you think I named her Luna?
as for the tips, all my mons I used had 252 EV in Speed and the primary Attacking Stat as well as 31 DV across the board.
Of course I still have to work at Coverage Attacks, so Tempest has to learn Heat Wave, I will replace Luna's Psycho Cut with Zen Headbutt, Ivy and Autumn unfortunately don't learn any attacks that could give them coverage, as far as I know. Crasher Wake knows Ice Punch already, the same is true for Greninja as Ice Beam and Extrasensory, but I need a Fire Type, maybe I swap Autumn for Volcarona when the time comes. As for Centurion I will teach him Rock Slide or Stone Edge and probably Poison Jab and Night Slash
