This Gym is home of the Fairy-type trainers and Gym Leader Valerie. You'll breeze through them if you have powerful poison and steel moves; however for Dragon-type trainers like me, you'll be forced to swap a few members of your team and replace them with Fire, Poison or Steel-types. You can use your Dragons if they're the main staple of your party; however, you'll need to rely on non-dragon attacks and make sure they're power-leveled to defeat the fairies with one-shot and to make sure they get to attack first. Aside from being bane of Dragons, Fairy-types are also strong against Fighting and Dark-types.
The layout in this gym is a bit different (and probably the best-looking gym yet). You have to use the portals to reach various rooms until you reach the gym leader. You may refer to the map below to know which portals lead to where. Fortunately, the portals are two-way so you can quickly find your way back if ever. The route with the least Pokemon trainers is 1-2-3-4-D-E while the route with the most trainers is A-B-C-D-E.
Furisode Girl Kali (Prize Money: p2,736)
Dedenne can be annoying with its Volt Switch move but as long as you can take it out with one-hit, then it shouldn't pose that much problem. Azumarill will use Aqua Ring which will continuously heal its HP little by little. This wouldn't be a problem as long as your attacks deal heavy damage that its regeneration effect won't be able to keep up.
Furisode Girl Linnea (Prize Money: p2,880)
Frail and should be easy to defeat. However it will pose difficulties to male Pokemon due its Attract and other supporting skills.
Furisode Girl Blossom (Prize Money: p2,664)
Nothing special to note here; her lineup shouldn't cause you problems.
Furisode Girl Katherine (Prize Money: p2,880)
This is Aromatisse's counterpart. It is a bit resilient and watch out for its powerful moves like the Grass-type move Energy Ball. It can also drain HP which can be a problem if you can't defeat it quickly.
Finally, you have to face the Gym Leader herself. Heal up your Pokemon and hop on the final portal to reach her room.
Gym Leader Valerie (Prize Money: p6,720 )
Mawile can be easily defeated using strong Fire or Ground attacks. Sylvaeon seems to be Valerie's ace as it has strong special attacks and can effectively lower the attack stat of your Pokemon by two stages. She will also use Hyper Potion on it consistently so don't hesitate to use items whenever necessary. Mr. Mime isn't a challenge at all so there's no special tactics needed to defeat it.
Reward:
After the battle, take the shortcut portal in the upper left corner of Valerie's room. Leave the gym and your friends will invite you to explore the Pokeball Factory. Make your preparations then head to the city's northwest exit to reach the Factory's entrance.
