This is pretty cool.
What tier threat list are you using though ? Like Thundurus and Chomp are off of it so it makes it look like Smogons but you still have Excadrill who is uber on smogon etc. Plus strange things like Kabutops on there (who isnt a threat in OU at all now with the Drizzle/SS shenanigans) which makes me think its for PO ?
I think the best thing to do is keep all of them on there tbh.
Another option would be to just include the whole tier lists from Uber > NU to let the player customize their threat list to suit both PO and smogon players, but id assume that would be a hell of a load of work. :/
