Personally, I find this to be a little be underwhelming - There should be more silliness involved than just a whitelist of allowed pokemon. Maybe add new rules to the tier, for example, any bird pokemon deal 1.5x damage, or all birds get instantly killed. There are tons of things you could do with this concept, but at the moment it seems lame in my opinion...
