Right now on Pokemon White, I'm trying to let my brother catch up to me in the main story, so I've just been leveling up my Pokemon, and I recently got an Oshawott over trade, and leveled it up to level 36 and evolved it for my Pokedex within like... 5 minutes.
I'm at the point in the game right before I fight the 8th gym leader whom, according to Serebii, has Pokemon around level 40. My team's all level 50s. I wonder who's gonna win. :/
All I did was train Audinos on Route 10. I would cycle back and forth in the non-tall grass, and wait for a patch to shake, then I'd fight whatever appeared. It was mostly Audino, but I sometimes got Sawks and Emolgas. I think it took like, 2 fights with a lucky egg to level up, while I was about level 40? :P
The sad thing is, I was using a Frillish, so the Audino couldn't even hurt me in any way. I got really easy training there. :)
Then I got Pokerus while doing it... I wonder how many HP EVs I got...
