Hi, template creator here! I'm gonna comment on some (hot) takes I have on this Tier List! (also, if you want any mon added to the template, be sure to let me know)
Wo-Chien: okay so I know I have nommed this mon to drop before, but after laddering with it and testing with friends, I have changed my mind on the Snail. This mon is super bulky and supports the cast of special attack really nicely. I specifically paired it up with Sylveon, Chi-Yu, and Iron Bundle on the team I spammed. For example this was a calc I came across:
252+ Atk Iron Hands Wild Charge vs. 252 HP / 0 Def Tablets of Ruin Iron Bundle: 230-272 (72.7 - 86%) -- guaranteed 2HKO
Scream Tail: this mon is... really versatile to put it lightly. It makes up for its terrible offenses with great bulk, speed, and access to really powerful utility moves such as Thunder Wave, Encore, Fake Tears, Stealth Rock, Psychic Fangs, Helping Hand, Trick Room, and even stuff like Howl and Scary Face which are admittedly nicher options. Although it has flaws (the lack of damage output as I said, and the fact that Gholdengo pretty much hard counters this guy), its presence simply cannot be ignored and a simple Thunder Wave can shutdown the fast offensive threats we have.
Maushold: Here is another mon that is really really versatile, but in a different way. Population Bomb can exert immense offensive pressure, as non-resists (that aren't called Iron Hands or Wo-Chien) take a lot from it. Maushold can further increase the pressure using Tidy Up, removing hazards and increasing its already high Speed and Attack stats. Combined with Technician and Bite to hit Gholdengo, it can get out of hand really fast. But what puts Maushold aside from the crowd of offensive threats is the defensive value. It gets access to a bunch of support moves, most notably Follow Me, Encore, and Super Fang. It can also completely ditch the offensive side and focus completely on supporting its teammate with Friend Guard and Follow Me.
Sylveon: Fairy attacks be really good this gen, and the scarcity really bumps up Sylveon for me. The special bulk, the power, and the utility comes in a nice package. Tera is also absolutely great for it, as Tera Blast provides it a single target Fairy-STAB before Teraing and provides it Fire-type super effective coverage against Gholdengo, Amoonguss, and Kingambit who would otherwise survive Sylveon's attacks and punish it with Make it Rain, Spore, and Iron Head respectively.
Few Notes on Playstyles:
I think both stall and hyper offense benefitted from Annihilape ban a lot. Stall gets to click weaker attacks without fearing giving Ape Rage Fist stacks, stuff like Snarl and Knock Off mainly. Hyper Offense also likes having to not care about what it clicks at what time, since one wrong click into Annihilape isn't an insta-loss. Rain and Sun are still pretty good, Tyranitar struggling and the sand abusers being lackluster puts Sand in an awkward spot, and Snow just hates the fact that the main reason it is used (the Aurora Veil) is prepared against because of the viability of Grimmsnarl. Glimmora Balance also likely gets better with Ape ban, again same with stall, throwing out weaker attacks like Icy Wind and Snarl is way less punishable (mainly by Kingambit, which I think also got better).
I wish everyone that read through a nice day ^-^
