Miltank is easy if you have a strong fighting type, or you want to be cheap and trade a Riolu egg over and evolve it into Lucario.. Heck, it even gives you an option to trade a Drowzee for a Machop (WHICH I AM DEFINITELY GOING TO DO).
Lucario would easily tear through that gym cause he LAUGHS at Rollout and if you have Aura Sphere, Miltank doesn't even stand a chance as its Sp Def is weaker than its uber high def..
-edit- I just got up to Whitney.. It took me three tries to beat her.. The first time, her Miltank kept FLINCHING MY MACHOP WITH STOMP and her pineappleing Clefairy got Energy Ball out of Metronome. The 2nd time, her Miltank's stomp did a critical hit >_> and killed my Machop. After that, I finally got the luck of the draw and took that fucking cow with two low kicks.
