Alright, just going to skim through the rankings and point out things that don't look right to me.
Gallade (Mega) A- -> B+
Been touched on before, competition with megacham more or less bars it from A IMO. Putting in B+ because its typing is still really good offensively.
Gyarados Unranked -> B+
Surprised this isn't listed. Gives trouble to Colossoil, Tomohawk (if Bounce), Diancie, has Earthquake coverage, beats a lot of physical attackers by virtue of Intimidate. Ground immunity is cool too, with the type being as powerful as it is.
Landorus A- -> A / A+
What made this worse in CAP? As previously stated, Ground is an amazing attacking type, and it still has the same qualities that make it A+ in ORAS OU. I guess stuff like Syclant make its job harder, but I don't think it's enough to put it in A-.
Thundurus A- -> A / A+
Again, what made it worse? Colo doesn't like mixed variants, hazard control is easier in this meta than in ORAS OU, panic wave is still as good as ever, and the ground immunity is a good boon as stated before.
Gengar B+ -> A-
Sure, loses to Colo, but being a Poison-type immune to Ground is pretty big in a meta full of ground coverage for poisons and the influx of fairies. Again, still has all of the qualities that make it good in ORAS.
Jirachi B+ -> A- / A
Relatively unaffected by HP Grounds, great fairy switchin, colo doesn't like Ice Punch or U-Turn, psychic STAB is nifty with poison types being relatively popular.
Hippowdon B -> A
As I said before, Ground is an amazing typing in the current meta, shares Colo's ability of being a Ground not 4x weak to ice, and sports reliable recovery which colo wishes it had.
Latias B -> B+
See Latios, just less so.
Latios B -> A
Colo's presense isn't enough for that large of a drop, hates switching into a Draco, psychic STAB is cool, Earthquake coverage is there if you want that. Fairies usually fall to Psyshock after a bit of chip, still has the same qualities as in ORAS.
Feraligatr B- -> B+
I just think this is an unupdated ranking, hits like a truck, beats colo, beats diancie, has Aqua Jet if you want that, Earthquake coverage, Ice Punch for Necturna, no LO recoil.
Suicune C+ -> B / B+
Again, what made this so much worse in CAP? Doesn't like colo knocking off lefites but otherwise beats, defensive cyc doesn't beat it after a CM or two.
