I just wanna add a few details that you might have missed.Lots of things
Frosmoth actually gets Defog and has Ice Scales to take advantage of its acceptable special bulk in 70/90 so this could be potentially forced into teams with Heavy Duty Boots.The biggest hit is without a doubt the fact that it has no hazard removal.
Clefable exists in Fairy.- Rock setter Mawile
Cobalion exists in Fighting.- Rock setter Terrakion
Pretty sure we can use Kommo-o as a good electric resist in the absence of HP Ice and not a lot of mons getting Fairy coverage.- No Electric Immunity/Good Resist
Thanks for putting up a good list tho, can you do Water when you have time?
