There's also the 2nd gym which, if you missed out on RoggenRolla and the Red/Blue fighting types, will cost you someone, with what is effectivly a BP 210 attack at the 2nd Gym Then there's Elesa. Those Emonga spam Volt Change so much. Rock types are 2HKO'ed. Ground types can't hit them with their STAB, grass types can't wall them, because they have AA, and Ice types don't exist yet. When they're getting weak? Hyper Potion... After that, it's somewhat easy, but man, the 2nd and 4th gyms are nightmares. In a normal in-game run, I had to use STEALTH ROCK [Dwebble] to beat Elesa, and half my team still wound up KO'ed... at Lv 30, 5 levels higher than her Emonga.
