This is the only pokemon game i've chosen a fire starter i nearly regreted it when I nearly couldn't beat the first gym, my pokemon are pretty low level right now, I'm up to the 3rd rival battle and i can't beat him...

I never lost a battle until I came to the twins. I think at the time I mostly relied on my Torchic/Combusken and my Zigzagoon instead of leveling up all my pokemon

I'm trying to keep my Pokemon as high leveled as i can, and around the same level, so it would be easier, I've lost a few battles so far... Um... Is there any attacks that are super effective on marshstomp? Grass? i don't have a grass type, but oh well. I barely defeated the rival, I only had my Poochyena left XD
