Depending on the team, I have different methods.
Stall teams take a long time and and a bit of commitment too actually build a successful one, what with plans to figure out how to bring down a aggressive offensive team, and to be able to cripple other stall teams, e.g. Trick Scarf Rotom-[x]. They need to find an effective way to stop CB Sally Outrages, and countering Scizors, Heatran, and Skymin., who can be stopped pretty well by a balanced tank Zapdos, if not a fully Special.
Offensive teams are complicated, I generally ask for one, test and change to suit my more conservative play.
