[OVERVIEW]
Cloyster is a unique, solid setup sweeper with Shell Smash + Skill Link on hyper offense teams. Its naturally high Defense lets it set up on physical attackers such as Zygarde-10%, Mamoswine, and Excadrill. After a Shell Smash boost, Cloyster can threaten many top UU threats such as Hippowdon, Salamence, and Amoonguss, with only a select few Pokemon able to revenge kill it at +2. However, Cloyster's lackluster Special Defense stat and initial speed prevent it from setting up against offensive teams with powerful special attackers such as Azelf, Nihilego, and Thundurus-T. Even at +2 Speed, Cloyster is outsped by common Choice Scarf users such as Zarude and Hydreigon. Cloyster cannot fit coverage for both Slowking and Primarina, and it just cannot get past checks such as Keldeo, Rotom-W, and Tentacruel. It is vulnerable to priority moves such as Lycranroc-D's Accelerock and Conkeldurr's Mach Punch, and can have its sweep cut short by status, Life Orb recoil, and entry hazards.

[SET COMMENTS]
With Skill Link, Icicle Spear, and a Shell Smash Boost, Cloyster can defeat many top threats, such as Diggersby, Celesteela, Tangrowth, and Thundurus-T. Pin Missile hits Ice-resistant Pokemon such as Slowking and, somewhat less importantly, Starmie, for super effective damage. However, Poison Jab is an option to KO certain Water-types such as Primarina and Azumarill. It also hits Keldeo and Rotom-W for greater damage. Hydro Pump is run to OHKO physically defensive Pokemon such as Cobalion and Skarmory after a boost. Life Orb secures these OHKOs, but it can severely cut into Cloyster's longevity. White Herb is an alternative that restores Cloyster's defenses back to normal after Shell Smash, limiting its vulnerability to Scizor's Bullet Punch and potentially letting it boost again. A Naughty nature gives Cloyster maximum Attack without weakening Hydro Pump, as it does not care about decreasing its already low Special Defense.
Cloyster is primarily a late-game cleaner on hyper offense teams, which are great at weakening its checks. Cloyster appreciates a dedicated suicide lead, such as Excadrill or Scolipede, to set up entry hazards and rack up chip damage on threats such as Celesteela and Swampert. Excadrill's Stealth Rock also disables Skarmory's Sturdy, and it can remove hazards with Rapid Spin, alleviating Cloyster's weakness to them. Celesteela and Azelf can take on Fighting-types such as Conkeldurr and Cobalion, with the former beating Scizor and the latter able to revenge kill Keldeo as well. Gyarados and Thundurus-T can remove Water-types like Keldeo, Tentacruel, and Rotom-W for Cloyster. They also can wear down checks such as Slowking and Primarina. Scizor and Meteor Beam Nihilego pressure faster threats such as Zarude, Azelf, Salamence, and Hydreigon. Scizor can revenge kill Azelf with Bullet Punch and take a hit from Zarude, while Nihilego uses both Salamence and Hydreigon to fire off Meteor Beam.
[STRATEGY COMMENTS]
Other Options
=============
Focus Sash could be used in place of Life Orb or White Herb to get off a Shell Smash reliably, but this item necessitates using a Taunt lead or Rapid Spin Excadrill to block or clear entry hazards. Heavy-Duty Boots can be run to mitigate Cloyster's entry hazard weakness, but, like with any item bar Life Orb, Cloyster will fail to get past Skarmory and Cobalion.
Checks and Counters
===================
**Fighting-types**: Fighting-types such as Conkeldurr, Cobalion, and Keldeo offensively pressure and KO Cloyster. Conkeldurr can also pick off Cloyster using Mach Punch. However, Cobalion is cleanly OHKOed by a +2 Hydro Pump.
**Bulky Water-types**: Bulky Water-types such as Rotom-W and Tentacruel can tank Cloyster's hits and KO it with Volt Switch or Sludge Bomb, respectively. Additionally, Slowking or Primarina can wall Poison Jab sets and Pin Missile sets, respectively.
**Faster Threats and Priority Moves**: Faster threats such as Nihilego, Azelf, Thundurus-T, and Salamence can take advantage of Cloyster's poor Special Defense and KO it before it boosts. Common Choice Scarf users like Zarude and Hydreigon can outspeed Cloyster at +2 and KO it with their STAB moves. Common priority move users such as Scizor, Zygarde-10%, and Lycanroc-D can also KO Cloyster after it boosts.
