A chance to improve your SCMS edit dominance: All those outdated BW sets for banned or unviable Pokemon that we "hid" by removing the Pokemon from the metagame file instead of actually deleting the analysis are now visible on the new dex. Stuff like OU Deo-S and NU Cryo and OU Klinklang and I'm sure a ton more. Given that BW tiers aren't shifting anymore, I think it's safe to just delete them now.
Get to work. n_n
