Help, /vp/. Down in my school we have a group of friends that each have a different region as their favorite. To make this interesting we decided to to have a "Gen Battle" where each of us are designated our favorite Gen and we can only use Pokemon of that Gen. Our tastes are pretty evenly spread considering there's 1 friend representing each Gen. I got Gen 3. Now my real question is what Pokemon should I use that is only from Gen 3 that will give me a competitive edge? Note, my friends are planning to use their favorite/best mons from their specific Gen. So It's all going to be OU basically. So, what mons, Items, and EV allocations should I use to have a viable team against these other threats?
