nah bro, what they need to do is make it special for unknown
let it learn hidden power every 10 levels or something, let it be able to know all the different types of HP, and then let each one have a different special effect,
e.g: Fire HP has a chance to burn
Ice to freeze
Fighting can lower opponents def
Steel raises your own defence
it'd be a gimmick, but even if it's not competitive it'd be fun to use, there's just no reason for it to even exist currently.
