Agreed on all of these. As a balance player, I find Bolt to be annoying to face. Calm Mind Booster SpAtk can straight up 1v1 AV Glowking and win, and then retain enough health to leverage a Tera and beat the revenge killer coming in. Predicting the Tera is annoying when Bolt is at half health. If you want to revenge kill with Great Tusk and think it will Tera, do you click Ice Spinner for the Tera Flying or Headlong Rush for the Tera Fairy? Pick the wrong one and you lose your Tusk.I am noticing higher usage of Zapdos(?) and Raging Bolt after Volc's ban.
Zapdos's increased usage is a bit strange since it didn't really benefit from Volcarona's ban. That being said, I think its return to stardom is likely influenced by Zamazenta's increased usage. I think Zama is frankly necessary in the metagame to contain most of the bullshit, but ID + BP Zama has a very straightforward and easy wincon - defeat Ghost and sweep. I've been able to break through mons as sturdy as Gking and Gliscor with it, which is crazy. Thankfully, Zapdos acts as another stopgap by crippling these ID + BP sets + trolling in general with para. Its good into a number of mons like Tusk, Teal Mask, Lando-T, etc. so it "arguably" fits into the metagame just as well as home / DLC1, though it works best it the opponent elects not to run Gliscor, Ting-Lu, or Raging Bolt. I've been trying to use Ghold Hstack more lately (without Air Balloon might I add) and something I find really annoying is how easy it is for Tusk to Spin against Ghold since its faster, so it can afford to mispredict by going for Ice Spinner or Knock. Zapdos is still nice on these teams as a way to disuade Tusk from Spinning so freely, while spreading Para easily to make it so that Ghold's Hex becomes more dangerous. That being said, you effectively have two mons with are useless vs Sun, Garganacl, and Raging Bolt if running TWave Ghold + Zap, so be careful. I think part of the reason Zapdos fell off (aside from Gliscor + Raging Bolt + Kyurem being added in DLC2) is how dependent it is on Hax. If it gets those Static / Discharge procs, its a god, otherwise, its just mid, arguably bad even. Hurricane is also a terrible move to rely on vs various threats like Lando-T.
I've been seeing a lot more Raging Bolt post-volc ban too. On some level, this makes sense since Volcarona was arguably one of the better Pokemon at 1v1ing Raging Bolt with QD + Tera Ground. Nonetheless, I find this development very unfortunate. It is absolutely a skill issue (bolt isn't nearly as effective in my hands compared to the opponent's), but I just HATE fighting this mon. Raging Bolt players need to make the simplest read ever by clicking Draco on a Ground-type switch-in (specifically Tusk or Lando-T) and there will be very little stopping it from claiming 2-3 kills later on when it inevitably Calm Mind's -> Tera's on its "check" -> Calm Mind's again. I've been trying to build more teams around shitmons and I find this mon to be by far the biggest gatekeeper - even bigger than Gambit - since its very easy for it to setup and spiral out of control. Tera on a mon this bulky just isn't fair. There was an instance where I was staving off an opposing Bolt with my Iron Treads and Bolt was doing more to Treads with +1 Booster SpA Dragon Pulse than I was doing back with Ice Spinner (Raging Bolt was Tera Flying). And I had a significant amount of Spdef investment too! At the very least, this is a mon you can use too. Compared to Ghold, I find Bolt to be a lot more consistently useful, since its defensive utility is more applicable against offensive styles (specifically Sun and Woger) and if the opponent doesn't have Clodsire, its fairly good at weakening defensive cores.
Another mon I've been seeing more of is Iron Crown. I think this Pokemon's potential is only going to go up as more bans happen (though a Woger ban might not neccisarily be good for it), which I think is good! It can be a bit linear in how its played, but it does a really good job at filling in a Lando-T-esque role with its FutureSwitch Combo, deleting opposing leads with Tachyon Cutter, punishing Tera Fairy on mons like Bolt, etc.
Speaking of Zama, I can see Hatterene being a decent option to check non-Heavy Slam sets, particularly the ID + Roar sets that have been popping off lately.
