First i found a thread on team building and read it. then i looked at pokes i could breed and what jobs they could fill based on stats. i tryed to stay away from the common OU's like skarmorary and infernape. Instead i used very powerful but very easy to get once you have a lower form of it pokemon. so i figured out pokes that were overlooked but still very strong. i used smogon a lot for this. some i figured out by reading other posts.
how did you figure out a team?
