Fire type are a real pain to get in 4th gen. Rapidash & a starter are you only options.I always choose thngs that can cover the gym leaders and E4. I also try to get Fire, Grass, and Water all in my team. A flyer(if I like any of the fying Pokemon) and usually no legendary..
So, how do you build your team?
In platinum, Rotom is outclassed by every other electric type in the game unless you use one of its forms, via mystery gift.Yeah, I sometimes change my Pokemon on the fly. In Platinum I ended up getting Rotom haha.
That whole fire starter and psychic thing would really work out in 4th gen hahaI don't battle competitively, so I just use Pokemon I like. My team usually goes like this:
Starter (Usually Fire)
Random Type I happen to like
