This isn't a very surprising suspect to see, but kind of surprised it's the next one after Hera. I'm actually pretty mixed on Reuniclus, and probably won't bother laddering for reqs this time around, but if I can add on an early part of the discussion I'll do so.



What Reuniclus brings to the table is the ability to threaten passive playstyles or people using sub-optimal offensive Pokemon, which isn't a bad thing, it is something teams have to take into account when building that you can't expect to win with a bunch of bulky Pokemon who spam hazards / toxic and call it a day as it avoids damage with Magic Guard and it's super fat with that 110 base HP with respectable 75/85 defenses.



Given the affinity for a lot of defensive pivots the tier currently has, the blob has a lot of set up opportunities to invoke damage against opposing teams with the Calm Mind set which means that teams usually have to rely on having soft checks or making sure they can generate enough offensive pressure that Reuniclus doesn't have any breathing room beyond coming in and setting up one CM or recovering off damage, however I do also think the tier has enough powerful Pokemon that against certain balance and offensive builds Reuniclus can be marginally dealt with as unboosted it can take a lot of damage from special attacks, and it's damage output in general can be lackluster giving Pokemon who can at least take a 0 or +1 hit the ability to inflict some serious damage on the blob before either dying or forcing it out into a reserve spot for when it can take advantage of an opposing pivot again.



I'm not really a big fan of the OTR set, I always seem to have a hard time finding a way to build a team that compliments the set, and it's not like you can just slap it on a team like you can the bulky CM set that just absorbs every hit. I know it is very powerful in general, and it can give teams trouble, but I always find it hard to set up a TR and then sweep the opponent as there are various Pokemon that can tank a hit and just do some great damage right back at you, not to mention I really dislike having to rely on focus miss for Dark types especially when Umbreon is a factor and it can waste out TR turns with Protect and Wish healing.



I think what might be the straw that breaks the camels back on Reuniclus for some people is that with a Z-Crystal Knock Off does significantly less damage to Reuniclus, and you aren't hampering it in any way by removing it's item. It gives it a lot more durability to tank hits even from Super Effective or STAB KO users to at least be able to kill them with a Z-Move and the possibility of retreating out to take advantage of said bulky pivots the tier likes later on to recover if need be on them.



Also on the topic of having to use Skill Swap Cress to remove it's immunity to Toxic. Fun thing I learned because I didn't know Toxic and losing Magic Guard worked like this, but you take all the accumulated Toxic damage you were supposed to receive at once. So if you are out there for 6 turns with Toxic on you, and then they skill swap you on the 7th, you take 7 turns worth of accumulated Toxic damage. I actually thought it'd start with turn 1 damage, but lol nope, full on everything at once. Fun stuff Pokemon mechanics right?



Anyway I'm entirely mixed on the blob, it's head and shoulders above the other psychics we have due to status immunity, a great way to keep passive styles in check especially since its match up against offensive based teams isn't all that great. Knock Off power being reduced by Z-Crystals as well as Reuniclus' ability to stay healthier over the course of a match than threats you can threaten it with might be a breaking point for many, so I wouldn't actually be sad to see the blob go as it could in fact lean to a somewhat healthier meta, but I'm not sure that would be for the best at this junction in the tier. It serves as a pretty stable pokemon who can be overwhelming once it gets going, but can be managed with enough offensive pressure.
