Landorus-Therian:
A+ --> S
Metagross (Mega): N/A --> A
A makes sense for it, as its a very cool mon that has to compete with scizor around every corner.
Altaria (Mega): N/A --> S
So powerful, So S-rank.
Landorus: S --> A+
Losing out on lant, who is one of the best mons in the tier atm because of its versatility, may single handedly make this A+. Lando-i is inconsistent as a whole at times, because hurrimiss misses and oblivion wing sometimes doesn't do enough damage. Against stall teams it just destroys things, but against more offensive teams its just inconsistent
Sableye: S --> A+
Its so influential that the metagame is catered to it. If its usage drops, we're only going to find it in S again soon anyways.
Braviary: C --> B
Maybe even B+. I have tested Defiant pretty thoroughly and its amazing whenever there is parting shot around. A Shell Smash set is pretty good as well because of how offensive the metagame is (and the fact that it has a slightly better speed tier than diggersby).
Magnezone: A- --> A
I like it more at A-. Mag is very matchup reliant, and in all honesty it tends to be almost deadweight against some teams. Sometimes I feel like it would be better to use a steel lure instead of magnezone. It has its niche, but at this time I am noticing checking setup sweepers is more popular than countering them.
Tyranitar (Mega): S --> A+
I don't have that much experience with MTar, so I will leave this to others.
Rotom-H: N/A --> C+
Maybe even B- as this is becoming somewhat common and very effective. With all the offensive steels going around, it is becoming pretty good, as well as having the ability to mess with mega altaria should you choose to dedicate a moveslot for it. Its typing is pretty awesome in this meta.
Garchomp (Mega): B+ --> B
yeah, its competing for a very coveted mega slot right now.
Garchomp: B --> A-
B+ might be better, as it tends to be a bit inconsistent, but I haven't used it too much and have only seen it often. I haven't felt like its that good, but I'll leave it to you
Chansey: A+ --> A
maybe even A-, because there are like 3 common special attackers in stabmons right now and all of them beat it (keldeo, latios, landorus (knock off)). Transform is a nice little buff, but honestly the physical nature of the metagame is NOT kind to it.
Venusaur (Mega): A --> B+
B or even B-; see mega garchomp. Mega Venu is...decent, i guess, and can check mega altaria and most keldeo. Problem is that its not doing too much else right now.
Amoonguss: A- --> B
Should probably be a rank up from mega venusaur, mega slots are coveted atm and amoon has regenerator to help its case.
Espeon: B+ --> B-
B- is a little to far to fall, how about B? Espeon is still a good magic bouncer, and it is great to use it to bait all kinds of mons. I find using it with a defiant mon a lot of fun because it baits parting shot. Its a decent stallbreaker and a cool lure, and it can probably fall a bit, but I am tempted to wait on it going to B-
Gardevoir: B+ --> C
Geogarde would be awesome if it had a better movepool and steels weren't everywhere, but the meta just isn't kind to it. C is appropriate.
Jellicent: B --> C
Aside from the fact there are better keldeo counters out there, keldeo isn't that common, and jellicent is the ultimate fuck you to keldeo and a few other mons. Jellicent doesn't...do...much right now.
Slurpuff: B --> C-
Bellypuff was a cool idea, but its just not that good in practice with priority everywhere.
Venusaur: B --> C
Why was it in B? I guess you can judge this because i would have it in D.
Bibarel: B- --> C
lol bibarel. Seriously, this isn't gen 4. Simple smash is cool but bibarel is pretty much outclassed by any other good normal type with basically no niche over them.
Starmie: B- --> C+
Never used it, so will leave this one alone.
Gourgeist-Super: C+ --> D
Sure its a diggersby counter, but tbh who cares. Its so niche its not worth a teamslot on ANY team right now.
Sawsbuck: C+ --> C-
Old news, its a very niche mon.
Flareon: C+ --> C-
Again, niche as hell. If you like guts v-create and extremespeed, go for it, but imo its outclassed by ursaring as a guts mon who is outclassed by diggersby as a speeder.
Lopunny (Mega): N/A --> A+
Cool Mega that I guess could be A+, although I want to start it more in A. Fakespeed is outclassed by diggersby, so the main reason is scrappy fakespeed with scrappy kick, which is good, but diggersby is used as a revenge killer atm and diggersby counters aren't that common. If Lop took a role other than revenge killer, it could be a nice A+ mon, but I don't see it taking over one of those roles just yet.
Pidgeot (Mega): N/A --> C+
Boomburst + Hurricane is cool, but as was the case with mvenu and mchomp its just fighting for a hard to get mega slot right now. Agreed.
Slowbro (Mega): N/A --> B
Idk what its going to do besides be a catch all physical wall, and it might be decent at it as well. B is fitting.
Sableye (Mega): N/A --> B? idk
C+. See Mega Pidgeot and the others, while its also its base form is much more useful. MB is okay, but espeon is good for that, and Sable-mega doesn't get all that much for it to use to separate its role from regular Sableye.
Diancie (Mega): N/A --> B+
Better magic bouncer than Sableye, can probably be a decent rock polish sweeper or something since it no longer needs to go mixed (should probably go physical with play rough and stone edge, though), and looks like a geomancy set that takes advantage of its speed resistance and ability to force switches could be cool. Overall it may be best in a polish role, because of its lack of good movepool to abuse magic bounce, and the prevalence of steels makes it difficult to sweep. B, maybe B-.
