I haven't posted in this thread lately, but I'm bored, so here we go.
A+ -> A: This makes a lot of sense and is kinda of overdue since Hippowdon is a huge momentum sapper, and with all the offensive ice, water, and grass types running around, it is forced to heal way too much and you really can be put at a disadvantage in many games because of how much momentum this thing gives away, and it needs to be on a high level of HP to check the things it is supposed to check anyways. However, Hippowdon is a really good electric check along with being a decent talonflame check (but not general birdspam since mega pinsir hits like a truck) along with setting up rocks for the team and having whirlwind so that things don't set up on it. Hippowdon suffers major 4MSS since it wants stone edge to check talon, whirlwind to stop setup sweepers, crunch to lure gengar/lati, and toxic to wear down mons in the last slot (eq/rocks/slack are needed). All in all it's a pretty good mon, but its common weaknesses and momentum losing are why it should go down to A rank.
A- -> A: Haven't used raik much lately, but cm sets seem to be rly good, and it can run toxic for grounds. Also, the Assault vest set can make a great electric/torn check and the specs set hits like a truck.
A- -> A: Serperior is really good right now, and it has a lot going for it. Most teams have water/ground/rock types quite commonly and serperior can steamroll teams quite easily after it gets the first leaf storm off. Many people say that Serp is weak, but if you bring it out on a water or ground type, then you basically get to +2 for free because they are either forced to switch out if they want to keep said mon, or they can sack their water/ground type that is basically setup fodder for serp. Serperior also can dismantle defensive teams with taunt sets because it stops stallmons from healing or wearing serp down with toxic. However, Serp has a few common checks and counters, and that is why it isn't A+ or S rank.
B -> B+: I don't use goth stall much so I'm not going to say much about this one, but it probably should rise since it beats some common answers to stall like tricking a scarf onti manaphy so that it can't beat blissey 1v1.
B -> B-: Another mon I don't use much, but it seems to be a solid lati switch in along with a cool useful defensive typing and being a defogger/rocker, so I'm going to say stays at B rank, especially since it has many utility options like roar, defog, rocks, etc.
A -> A-: You guys probably already know my position on this mon, but if you don't know,
here it is (my reasoning there says that it should stay in A because of its strengths, but i understand it probably shouldn't go to A+ because of its weaknesses). Also, this post by user:
Puralux shows some other merits megabro has to keep it in A rank:
I really think that this might be one of the most underrated threats (and bulky win conditions) out there. I disagree that regular calm mind slowbro can take 'the same' place but without taking up the mega slot. We have to count that regular Slowbro needs to be full defense, because if you invest a lot in spdef on the purpose of being stopped harder by things like his checks after one calm mind (slowbro mostly needs this), you will end up in being stopped by physical attackers, and you can not switch in some powerful physical attacks, unlike classic full def slowbro. Sure, you lose regenerator which is a very important ability for Slowbro; because of this, you need to know when it's the moment to mega evolve Slowbro (to keep your momentum), which in my opinion compensates the loss of Regenerator with his insane capability. While you will have a kind of disadvantage in terms of bulk when you keep normal Slowbro with Mega (SpDef) into his normal form to keep regenerator, Mega Slowbro can be a pain in the ass to deal with. His insane bulk allows to deal with both physical and special attackers. You will have over 400 points of physical defense with Mega Slowbro, even if you invest a lot in spdef. You will end up having a stupid, lazy and ignorant pokèmon which is impossible to even break his armor to kick his ass, even after one calm mind. Shell Armor will keep a safe spam of slack off as you don't fear critical hits, you can also choose to modify your Evs according to your weaknesses. Like slowbro, mega slowbro doesn't appreciate status, especially bad poison. Even if you try to status mega slowbro, it won't be enough to stop him from slaughter the opposing pokes by dint of boosted Scalds and Psyshocks. So even if you wear down mega slowbro thanks to status, or by other stuff, he has probably already done his task: destroy the opponent's team, or at least, a great portion. He has flaws, mostly due to the loss of regenerator, difficulty to recover if there are hazards and sometimes the obligation of sacking it, and these flaws might surely let Mega Slowbro unable to satisfy A+ or S rank even with these incredible capabilities, but nonetheless, it's surely worth for A rank.
B+ -> A-: I Don't rly use this much, but probably should rise since spore is guaranteed to cripple a non-grass mon, and the sand teams that are popping up more and more now get rekt by breloom's STAB combo. Technician boosted mach punch coming off of that attack stat hurts like a bitch, and it is an excellent revenge killer along with being a decent answer to all the darkspam that's happening rn.
A -> A-: It really should be below offensive starmie and latios since it is much weaker/doesn't have good coverage, but can be used defensively decently well, but is generally outclassed on the offensive teams it is used on in the role of offensive defogger. However, its defensive merits should keep it in A- along with the utility of healing wish.
