Can I beat Cynthia with this team in Diamond?

My team in Diamond isInfernape lvl. 60 Moves: Flare Blitz, Earthquake, Rock Slide, Close combatRoserade Lvl. 57 Moves: Toxic, Ingrain, Petal Dance, Water SportCrobat Lvl. 59 Moves: Fly, Poison Fang, Confuse Ray, Air cutterFloatzel Lvl. 60 Moves: Surf, Waterfall, Ice Beam, CrunchLuxray Lvl. 55 (yes I know, but back in gen 1-5, exp share was basically useless) Moves: Thunderbolt, Thunder Fang, Crunch, StrengthKadabra Lvl. 53 Moves: Future sight, psychic, Trick, Miracle eye

i have fought Cynthia in Platinum and I won due to the level decreasing, but I don’t know if it will be the same in diamond because I have already lost. TWICE!!! Thank you.

Btw, I tried the focus sash, trick troll on Cynthia and it got me down to my infernape and her lucario. I used flare blitz then it KOed it. I thought I won, but the recoil killed me.

EDIT: I grinded my team for a month in victory road and now it looks like this:Infernape lvl. 70 Moves: Flare Blitz, Close Combat, Grass Knot, EarthquakeFloatzel lvl. 68 Moves: Surf, Ice Beam, Crunch, Bulk Up (To tank Garchomp hits)Roserade lvl. 68 Moves: Petal Dance, Grass Knot, Sludge Bomb, Toxic SpikesLuxray lvl. 70 Moves: Thunder Fang, Crunch, Strength, ToxicCrobat lvl 69 Moves: Cross Poison, Mean Look, Fly, Shadow BallAlakazam lvl 67 Moves: Psychic, Calm Mind, Energy Ball, Shadow BallWill it win now?

I would say yes.The thing is you need to level up your Pokemon first. (They are a tiny tad low)

If you ever think you might loose… level up your Pokemon.(Works every time)
