I agree with akuto wholeheartedly on this, and I really like projects like these because they teach me how good players build their teams (not just throwing stuff together nilly-willy like I do XD). Also, though I have tried weather+hazards+spinblocker, I've never thought about using Latios before (why is that?) and I have only started using Terrakion recently, after it was brought up here. (thank you!) Even if we don't learn anything particularly interesting about the metagame, say, if it was like what jackm said, "Offensive Weatherless in Ubers is doomed to cookie-cutter syndrome.", I/we will still gain the knowledge of how to build better teams. :) Also, for the team, I like Arceus-Ghost over Latios, as it has some different weaknesses/resists from Latios. Also, SD Arceus-Ghost is pretty rare right? (But I've seen it used pretty well by a friend). However, we'll probably need some surefire way around Darkrai if we do so!
