Here is my review on all the pathetic gyms of Hoenn ^_^
Roxanne is an easy one, it just takes extra time with Torchic (evolve it to Combusken...not that hard.)
Brawly is a loser, you don't even need a Flying or Pyschic Pok?mon to take him out.
Wattson is a little toughy. Well...no I lied ^_^, Unless you have Marshtomp or Combusken, you can obliterate his team. (Magnemites Fall with Combusken's Dual-Advantage)
Flannery is so pretty I didn't even wanna beat her..oops. Simple, even with Grovyle (well...just don't use it in battle...find a diseased Sandshrew or other Pok?mon and train it to capacity!)
Norman is a little *****... Even with a fighting type, he can still be hard -__-;. You'll find a strategy eventually like me ^_^...really now..
Winona..Oh man how pathetic.. you might not want to use an Electric type when you go to battle her though. Use a Water-Type with an Ice-type attack, simple as pie ^_^.
Tate and Liza..Dynamic *****es :0 I mean, Swampert/Blaziken with Mightyena/Other Darktype and follow that up with either: Ninetales/Raichu/Altaria It really gets the job done, no fuss no muss.
Wallace is so sad he shouldnt even have a harem and or fan-club -_- the only thing hard about this gym is the little puzzle at the end. Other than that, use A GRASS TYPE and back it up with: Electric and Ice types...you will really love yourself if you do that, if you don't win by your third try...may god help you.
