Hey, CL, nice of you to join PC…
Anyways, You can't use two of the same item in the Battle Frontier, willy. Give Shiftry a Lum Berry, you'll need it. Don't put Dark attacks on Shiftry…it can't learn any strong Dark moves so they're not worth it. Get Explosion so you can kill something when you're about to die. Brick Break can help against Steels, and special walls like Snorlax and Blissey. But you might wanna keep Shadow Ball for Ghosts like Gengar.
Shiftry @Lum Berry
Sunny Day
Solarbeam
Explosion
Shadow Ball/Brick Break
Don't put Earthquake on Blaziken. You should never have Ground attacks on a Fighting Pokémon (unless they can't learn anything better). Fighting takes care of most of the same types that Ground does, but Fighting attacks will be more powerful since they get STAB from them.
Blaziken @
Sky Uppercut
Swords Dance
Rock Slide
Overheat
Buy Rock Slide and Swords Dance from the BF shops once you have enough points.
For your third Pokémon, you need something with a lot of defense. Pokémon like Salamence and Aerodactyl will give you BIG problems. You need a Water that that preferably knows Ice Beam. Milotic works great. If you can start another game, you can get a Swampert. If you can trade from FR/LG, you can get Suicune, Vaporeon, Slowbro, Cloyster, or Lapras.
