I was hooked up over Colupis' post on Ceruledge, so I wanted to give my opinion, because I could also see his point while thinking otherwise. But first, I want to share my opinions about which used Pókemon most of people use (or which I would use) to hold Ceru back.
Why Alomolola specifically? Well, I think you all know how nasty defensively 'Mola is, so it can use either Toxic to stall it out, Protect to scout the Z-Move and STAB Flip Turn to hurt it (Also keep in mind your giving it a boost). Also AV sets could also run STAB Aqua Jet to surprise it or STAB Liquidation to stoop its health short enough in range of Aqua Jet.
Well, Samurott's Typing Combo speaks for itself, so I don't think I need to say much, however it Ceru' doesn't have Close Combat and you keep Hamurott alive and well, you wall ceru' good enough to not be a problem for you. Outside of hitting it witzh STAB Ceaseless Edcge and Razor Shell, Hamurott can also screw it Ceruledge using Encore of STAB Sucker Puch or STAB Aqua Jet.
I think Colupis made his point already with the Sucker Punch mind games, though I wanna add that ifd there's Psychic Terrain and both Kingambit and ceruledge are grounded, Kingambit is in trouble. Outside of that its interesting, because neither of them are truly safe from one another: Ceruledge think the gambit is going Sucker Punch, but it goes into STAB Knock Off.
Here's probably my favorite wall to deal with the shenanigans or Ceruledge. Giving how monstrously builky Ting Lu is, its no surprise it can tank every hit from Ceruledge that is not Close Combat. STAB Earthquiake kills, and if Ceru does have Air Baloon, Ting Lu just STAB Ruination or Rock Slude into it. Even in the case of Close Comabt, Ting Lu is bulky enough to outlive a Close Combat (not a boosted one). Also it has Whirlwind, which Ceruledge doesn't exactly appreciate.
I think Tusk if a far better wall and adversary for ceru than anyone else. Given its great HP and physical bulk, Tusk has no issue of tanking hits (even the boosted onesif Tusk is at full health) outside of Ghost Z attacks. Where Tusk really can scre Ceruledge is when it uses eithe the Defensive set or the Bulk Up sets (Since Booster up is used, Great Tusk won't have an item anymore, which makes it immune from Ceruledge's STAB Poltergeist). Defensive sets are just THAT bulky while Bulk Up ste you have Max HP and you can still set yourself up to be hard for Ceru' to break.
The defensive sets with Intimidate, invested Bulk on HP and Defence while being enogh fast to outspeed Ceruledge means it can be a good way to deal with it. Having Taunt on Lando also helps it screw Ceru's Plans on set itselfzup with Swords Dance. STAB Earth Power, while not being popular is EXTREMELY bad news for Ceruledge, because it leaves it with no double speed with Weak Armor.
Zamazenta needs no introduction. Its strong, fast, bulky and has the option of going Crunch (ALWAYS go Crunch) or Stone Edge. With or without the boost of Dauntless Shield, Zamazenta can deal with Ceruledge well enough if used correctly. You just need to watch out for the Z-Crystal, IF there could be out. Outside of that you should theoretically be fine, thoght still something you need to keep an eye for. As for Iron-Press sets, you shouldn#T have problems, given you maxed in HP and speed and you should have Crunch.
This one is interesting, because if Ceruledge doesn't have Close Combat, it's WALLED by Tyranitar Mega, which Mega Tyranitar can use STAB Pursuit to outright KO it. Given Tyranitar's typing, It naturally walls Ceruledge like nothing. Though if it DOES have Close Gombat, well...
I also want to mention Pókemon that even if the don't outright deal with Ceruledge, are factors that Ceruledge doesn#t enjoy.
:Lopunny-Mega: :Urshifu: :Scizor-mega: :Rillaboom: :Raging Bolt:
While Weak Armor is an amazing ability, the con to it is that you weanken your defense stat, leaving Seruledge vulnerable to all sorts of priority moves. While I talked about Sucker Punch and Aqua Jet from the likes of hamurott, Kingambit or Alomomola, there's also Urshifu who often or not uses Aqua Jet as a form of priority, which Ceru doesnt like. mega Lopunny also has priority like Fake Out AND Quick Attack. Alos Prioprity Moves which normally wouldnt be a problem for Ceru COULD be an issue for example a Grassy Glid from a Choice band Rillaboom and STAB Technician Bullet Punch from Scizor-Mega or a STAB Thunderclap from Raging Bolt.
I Also think of many other stuff that can hinder Ceruledge like strong special attackers (ESPECIALLY the ones that are super effective against it like Earth Powewr from Diancie Mega, STAB Shadow Ball form the likes of Choice Scarf Gholdengo or Pecharunt) and most notably being weak to hazards. Plus Ceruledge is threatening if you LET it set itself up. You just have to bully it enugh so it doesnt even want to go for Swords Dance. Ghostinium Z sets are popular but you dont have Close Combat, therefore being weak to some of the mentioned Pókemon. Air Ballon is also nice, but you lack the breaking power of the Z Cristal Ceruledge definitely wants. Weakness policy sets have the problem that you HAVE to hope that the opponent makes a foolish move to have a pseudo boost, however that plan can be easily be exploited by either using special attacks hazards, just Pókemons using normal coverage against it, priority or by using Encore.
Overall, I think while ceruledge all around is great. I dont exactly see it as an overwheliming issue liek something like Dragapult was. I think you just have to have an asset (Offenisvely and Defensively) you have to have on your team and I think you should be fine as it is. Just like Wellspring, Ceru can bve a svcary sweeper, but you could always plan something to deal with Ceruledge.
