How do I beat Cynthia in Pokemon Platinum?

Question

I've been stuck on Cynthia for quite a while now, my team consists of a level 56 Empoleon that knows Blizzard, Surf, Flash Cannon and Drill Peck, a level 49 Roserade that knows Sludge Bomb, Shadow Ball, Giga Drain and Toxic Spikes, a level 46 Gallade that knows Psycho Cut, Leaf Blade and Earthquake (yes I am aware that he only knows 3 moves thanks), a level 51 Houndoom that knows Iron Tail, Flamethrower, Dark Pulse and Thunder Fang, a level 50 Crobat that knows Fly, Cross Poison, Steel Wing and Bite, a level 50 Mamoswine that knows Earthquake, Rock Climb, Rock Slide and Avalanche, a response would be appreciated, thanks. :)

Keep battling her until you beat her. You should get a lot of experience every time you go through the Elite 4.

Answer 1

You are seriously underleved. Just grind up a bit and then take her on, above 60. Use the berrys that reduce damage from certain move types if you like. As for strats, I don’t really have many good ones. Empoleon can handle spiritomb, mamoswine will get rid of Garchomp, Crobat for roserade, roserade for milotic, and used houndoom or Mamoswine for lucario, the latter only if houndoom can’t outspeed. (Give houndoom the berry for reducing damage from fighting type moves.)
Hope it helped.
