Hey, I'm currently the lead on these kinds of things. The reason the PU sets are so empty is because PU only started existing a couple of weeks ago and we're giving a little bit of time for good Pokemon to be discovered, things to be banned, best sets and tera types to be figured out, etc. before anything starts up. There will be a whole process where we get sets uploaded but I'd rather not jump the gun quite yet. Just from the PU Kickoff tour alone I've seen a lot of meta development where people realize certain Pokemon/sets are quite good, not to mention the whole Oricorio ban. When we do start working on and uploading sets that'll be announced on Showdown, forums, and Discord and you're more than welcome to come help. We could definitely use more contributors! That being said, this thread can probably be locked up now since there's nothing to do but wait a little more for analyses to start up again this gen.
