More changes I'm bringing up. I'm surprised I left these out when analyzing the list previously.
Would anyone oppose to Weavile dropping to
C+/C? I think it's rather lackluster (just make sure you're not careless when teambuilding and pack four+ guys weak to Ice).
Clefable should definitely not be in B.
C or even
D. It has never given evidence over the years of DPP that it's a top threat. Its ability is amazing and its movepool is amazing. However, the stats don't back it up. It has decent HP, but it can't take the heavy attacks in OU. The main selling point is being able to avoid entry hazards. Other than that, stall doesn't really care about Clefable. It doesn't actually threaten the defensive Pokemon, it's just another supporter with a different tool than than others (such as Cresselia who instead employs enormous natural bulk). Plus, what stall? Stall is certainly viable in DPP, but the game is extremely offensive right now.
Don't know why
Slowbro needs to be above
C. I think the Physic typing is too detrimental in its case, especially when it has no speed. You have reliable recovery, unlike Cresselia, but the game hits way too hard for you to not be always forced into using Slack Off and doing little else. Paralysis and especially Toxic, ruin it, and you can simply double switch him to limit his options.
Some may cry foul, but I think
Bronzong can drop a rank or two. Its typing and Levitate is perfect. However, it does nothing more than sit there and proceed to not heal itself. I can never support the team as effectively as I'd like. I also rather use Stealth Rock on a ton of other Pokemon instead, and his offense is rather meager. Explosion is always nice though. It's main use is to check some specific threats with its resistances and immunities.
Honchkrow should drop to
D. It's BL, but that's because of its power in UU. It has very little place in OU. The HP is tarnished by paper-thin defenses in addition to the SR weakness. Any attack will do a lot to it (very susceptible to priority). Sucker Punches from it are easy to see because it's forced to use it a lot because of the average speed.
I thought more about
Yanmega, and while the abilities are awesome, it will never compensate for the SR weakness. It can't really choose to alternately function as a staller like, say Moltres, can. It's stuck to offense. The Protect lead is too predictable as well.
C is probably more accurate than C+.
I looked and found several more to add to the list.
The two more legitimate ones first.
Alakazam for a C+ or C. Also,
Kabutops was forgotten. It's extremely powerful in rain. However, getting a Swords Dance is quite hard to pull off because of its terrible defensive typing and low defenses (besides Def). D is too low in my opinion, so
C seems fair, just use a good rain starter and invest in Screens.
A couple of throw-ins.
Tangrowth should probably go on the list. It's good decent stats except for SpD and Spd. Strong attacks, the usual grass utility moves, massive physical bulk. It's basically an alternate Shaymin. One of the lower ranks, I suppose.
Very old-school, but
Porygon2 should probably be on the list in a low tier. Trace is awesome and can compensate for the decent-but-not-amazing bulk.
a to c range could use some cleaning up but just to chime in on cress, i think its c at best in this metagame. s tier shits on it, sand is everywhere, and as a "general wall" it lends itself more towards being setup fodder. ive only seen it used with ridic support, ie a cm rest set paired with dug + zone a la mariano dragon, and its still an incredibly meh win condition even in a situation that favorable due to its glacial pace, piss poor damage, and vulnerability while resting. set basically falls on its face if the opponent has any extra offense or trick. i remember simply 1v1ing it with dd gyara in a tour match and countersweeping after hed trapped and killed 2 guys early for free. however, it did go to work on me one time at the hands of stone cold when i was packin a helpless stallier squad that completely relied on ttar for it :/. i liked how someone touched on a screens pivot tho because i think utilizing that in tandem with its unique move lunar dance could provide a more relevant niche as seen here albeit dusty af

Man, the memories.
Anyways, Lucario is still probably one of the best "receivers" of Screens + Lunar Dance.
