There isn't much to say though, and technically you can apply the Kyurem black thing to every pokemon. Well I'm just here to help so. Have you considered moving up pokemon with very OP hidden abilities? Particularly serperior who is very famously known to sweep entire teams with contrary leaf storm which boosts its attack by 2 stages every time he uses it.
Well, where do I start?... At first when you made the tiering system I though it was ok cause it's some sort of measuring power. But you went to far dividing the tiers, it's so confusing, it's almost like taking Smogon tiering system and dividing it even more. Simply put, imagine someone making a PT team, he would have to constantly check the list to see the appropiate abilities and items in the respective generation to play accordingly to the tier. To tedious in my opinion.
This is the main reason why on Smogon there isn't a division of pokemon that cant use baton pass and others that can, they simply ban the move so its less confusing.
Another aspect to look at is the purpose of this tier list. Smogon tiering system goes by popularity of the pokemon used on competitions in a way that excludes any Pokemon centralizing the main tiers, so more Pokemon can be used instead of just a bunch.
As much as I like the idea of an alternative to the main tiering systems we have to admit that creating one that actually works is not an easy task for this little community. You can instead create certain rules to play around like battle formats, I think that would be simplier for everyone.
This seems cool. Can't wait until it is fully made (if it isn't already and maybe even improved).
