Regarding Kyurem-W
So many of you are arguing that Kyurem has the most spammable attack in the tier yet you are all forgetting you have to get the damn thing onto the field before dishing out the damage you all are speaking so highly of. Applepie's post and a few others' have explained that it has absolutely no defensive synergy provided by its awful defensive typing and gets no opportunities to do what it is supposed to do - even if so, you'll have to predict right if you're holding specs because bulky waters and some steels do exist to eat ice beams as are fairies to absorb draco; the latter move even gives your opponent a free set up with Ekiller / xerneas / pdon, or some spikes up with ferro / klefki after use.
Back to the topic of stagnation -- Kyurem's contribution to team synergy. What leaves it so lackluster in comparison to other similar wall breakers such as Latios, Rayquaza, Salamence, and xerneas, is utility. The aforementioned Pokemon do either of the following: 1) find switch in opportunities in virtue of type advantage and or Ability, and 2) have some sort of supportive qualities on a defensive standpoint, or offensive standpoint. For example, the latis have defog / healing wish / memento in addition to their respectable offenses and special bulk; Xerneas has access to aromatherapy; Salamence with intimidate and access to defog; and, Rayquaza with its access to extreme speed.
Role compression in Ubers is crucial, and every Pokemon on a team needs to contribute to the defensive synergy (not necessarily by typing and bulk, but by the ability to check/soft check the metagame's most notable threats in any way given) in some way or another. Take Rayquaza, for example. Although it has underwhelming bulk of 105 / 90 / 90, and does share a 2x weakness to Stealth Rock with Kyurem-W, it is well worth the switch in if your opponent has a weakened GeoXern steamrolling through your team, and Rayquaza is your only way to pick it off. Kyurem White possesses no such utility or redeeming qualities outside of an immense special attack stat with good stabs that it gets no opportunities to use; and even if it does, the matchup dictates what Kyurem can do to the opposing team.
Against stall, the earlier mentioned water arceus is there to take ice beams all day and has the bulk to take Draco meteor and recover spam, then some more. Blissey is a hard wall to it. Kyurem never gets a switch in against Hyper offense lest you run Sleep talk on specs/scarf expecting it to be a Darkrai check, which by that point you're praying on roles after you have switched into Rocks and spikes, just to take bad dreams damage and die to a Life Orb Dark Pulse; all while, you're locked into Sleep talk which your opponent just uses for set up fodder if Kyurem wakes up. Balance is the only matchup that Kyurem is actually useful -- it's able to switch in on some things like Def Yveltal and Lugia and it's the only scenario where you are able to endlessly spam ice beam because chip damage of any kind just neuters these teams because of how much they role compress and over-rely on certain mons to be their one-check-all to so many threats. For example, staying in on Klefki and using Ice Beam twice is well worth it if you have a Mewtwo in the back that is now able to push past it with a single Psystrike on the switch.
On a separate note - people seem to be forgetting exactly what a wallbreaker is supposed to do. All they really have to do, especially in this metagame, is chip at walls. All of this overhyped nonsense like "Kyurem-W can OHKO Yveltal Lugia Primal Groudon Klefki and Giratina huehuehue" is bullshit because in practice, all of that excess power that Kyurem has is useless -- couple this with the fact it has no defensive synergy or utility, and this leaves teambuilders to either pick a mon that does have these qualities (LATI@S/MEWTWO/PDON), or to just use entry hazards (attrition) which frankly do the same thing as wallbreakers. Stealth rock in itself is enough to allow Stone edge ekiller to break through Lugia - why would I want to waste a team slot on Kyurem-W when something as simple as Stealth rock can accomplish what I need done to win games? Granted that I do want to use a wallbreaker, I'd rather just use something like Mewtwo which has access to Taunt, hits just as hard, has neutral coverage that is comparatively just as good as Kyurem's, and base 130 speed to boot -- this is excluding the fact that it also gets a physical set which forces your opponent to bleakly guess which set you're carrying the first turn it's played. Upon encounter of a Kyurem-W, you already know two of its moves -- each and every one of its set has the same bloody coverage moves and are in relatively the same power bracket, leaving it extremely predictable and checked by the same Pokemon.
I don't know if any of you here arguing for this recall when I posted my first RMT of a team built around Kyurem-W in the XY era -- if you do, don't; however, I must display the team to exemplify how impossible it is to build with such a useless Pokemon. The team had two variants: 1) Arceus Ghost / Landorus-T / Palkia / SpD Xerneas / SD Megazor / specs Kyurem; and 2) Arceus Ghost / Landorus-T / SpD Ogre / cleric Xerneas / SD Megazor / specs Kyurem. Right away you see a huge weakness to HP Fire Geomancy Xerneas (very viable then) in the first variant, and a SpecsOgre weakness in the second. The team one way or another was weak to one of the metagame's biggest threats and there was no way to fix this problem aside from removing Kyurem-W -- which of course would have ruined the entire purpose of the team.
In teambuilding, I was essentially burdening myself by fitting in a mon that contributed absolutely nothing to the team's defensive synergy for the sake of just using the damn thing -- replacing it with something like Rayquaza would have fixed the team's issues by sourcing another form of priority, Kyogre check, wallbreaker, and ground immunity to it. Ideally the team should have been: Arceus Ghost / Landorus-T / SpD Kyogre / cleric Xern / SD Ray / Sd megazor -- Xerneas's HP fire is weakened by ogre's rain so Megazor can countersweep or just pick it off, and specs Kyogre can no longer spam ice beam or spout against the team. In the version built around Kyurem, my only hopes of ever preventing xerneas from just sweeping were to chip at it with whatever it chose to set up on, sack Kyurem because it wasn't doing shit at such a point, and go over to Scizor to pick it off. Heck, even a Zekrom could have worked in place of Kyurem to fix the CM Kyogre and waterceus weakness. Anything could have replaced Kyurem-W to make it a better team -- a team with Kyurem-W is a team of five, and it's not resourceful of a teambuilder to waste a team slot on something that checks nothing.
Comparisons between Kyurem-W and Palkia
I actually agree with this comparison and think they should be ranked together in C+. Kyurem-W can spam Ice beam with the intention of just chipping at anything possible, but Palkia literally does the same exact thing. This is where I disagree on the general consensus of Palkia's performance as an attacker -- all the 50/50 bullshit between Pdon and fairies is not true because by God you aren't using a specs or scarf Palkia and your only viable option is Lustrous orb, which can switch between its STABs and hit Pdon hard with spacial rend if it dare even stay in, and you have Hydro pump to hit xerneas and Klefki -- despite that you lose to all three of these threats 1v1, assessing trade offs isn't particularly necessary because it really isn't checking anything in the first place. For instance, is chipping Groudon for your xerneas to sweep worth taking the thunder wave or rocks set on your side? If staying in on Klefki at the cost of paralysis means you get to hit it with fire blast and sweep with Latias late game, will you do it? Of course; the problem is, it doesn't fit on teams because it's just outclassed by other attackers that fulfill other roles -- just like Kyurem-W. Perhaps Palkia can be one subrank higher than Kyurem because it has a better speed tier and access to some status moves that it can viably run like Thunder wave and toxic; but, both Kyurem and Palkia inevitably funnel down into the same category as severely outclassed attackers.
