If anyone is interested in hosting a tourney on PS, I'd like to say that as of now pokemon showdown officially supports both Balanced and unbalanced hackmons as well as CAP, and streetmons is in the works. Any tier other than those (and for now streetmons) is doable, but it requires complete trust that each and every applicant both fully understands the rules and is not intentionally breaking them. This is not to say that they aren't doable, but you should keep in mind that you run a much higher chance of the whole thing getting ruined by one guy that dones't follow the rules (before LC was implemented in LC tourneys people using level 100 pokemon not getting caught until the finals happened more than I was comfortable with).
On that note, we guarantee nothing, but if a metagame gets popular in here, there's always the possibility of it ending up on site with its own ladder.
