Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I said this in the old thread I'll say it again, Blissey ONLY gets D rank BARELY because it has final gambit, otherwise it should be unranked completely.
You can go look at the old argument because I'm too lazy to type it again but in summary:
Primal kyogre = S, Regular Kyogre = Unranked...
Protean / Tinted / Contrary etc ray fuck just as many pokemon, and different ones which makes it even harder to counter, than ate ray. I'm not going to go run a bunch of calcs to prove that, it's just how 180/180 mixed offenses and a great speedtier works.
