Singles Movesets for Cloyster

Focus Sash → Shell Smash Moveset & Best Build

Nature Jolly (+Spd, -SpAtk)
EV Spread Atk. 252 / Spd. 180 / HP 78
Final Stat Values HP 135 / Atk. 147 / Def. 200 / Sp.Def. 65 / Spd. 124
Ability Skill Link
Held Item Focus Sash
Moveset Shell Smash
Icicle Spear
Rock Blast
Ice Shard

This build combines Cloyster's high Defense with the two-stage Attack, Special Attack and Speed boosts it obtains from Shell Smash to make it a physical attacker with fearsome speed. Focus Sash allows it to survive even attacks it's weak to, which, when used together with Shell Smash, allows it to even outspeed Hydreigon holding a Choice Scarf and take it down.

It's also possible to opt for an Adamant Nature to boost Attack instead of Speed, but this will cost it the ability to outspeed Choice Scarf Hydreigon.

Other Viable Moves

Liquidation A physical Water-type Move. A choice for when not using priority moves.
Hydro Pump Allows it to take advantage of the Special Attack boost of Shell Smash. When using this move, a Naive (+Spd, -SpDef) nature is preferable to avoid the Jolly nature's Special Attack drop.

Choice Scarf Moveset & Best Build

Ability Skill Link
Held Item Choice Scarf
Moveset Icicle Spear
Rock Blast
Liquidation
Smart Strike

By holding a Choice Scarf, Cloyster can catch its opponents off guard and knock out physical attackers like Mimikyu in one hit while they are still trying to power up. Because most players use the Shell Smash build described above, opponents won't be expecting Cloyster to strike fast and hard right off the bat.

Other Viable Moves

Hydro Pump Effective for hitting Steel types with high Defense. When using this move, a Naughty (+Atk, -SpDef) nature is preferable to avoid the Adamant nature's Special Attack drop.
Ice Shard A priority STAB move. Unfortunately, it doesn't pair well with Choice Scarf, but it's great to have when you definitely need to hit first.

How to Use Cloyster Effectively

A high-speed attacker taking advantage of its Defense and movepool

Cloyster combines a high physical Defense with its ability to raise its stats using Shell Smash. Its towering Defense allows it to take a hard initial hit from a variety of opponents, following up on the second turn after its Shell Smash by switching to a fast attacking role and seizing the first hit.

A perfectly suited Ability

Cloyster's ability Skill Link allows its multi-hit attacks to land 5 times without fail. These attacks are particularly useful for their potential to break Substitute and Mimikyu's Disguise, but typically are difficult to use due to their low reliability. Skill Link makes these moves highly reliable and invaluable in depriving opponents of any opportunity to power up.

Pokemon which can resist its moves

The moves learned by Cloyster are easy to resist by a number of Pokemon. Because of its multiple-hit moves, it's not possible to survive its attacks for a big hit with techniques like Focus Sash and Substitute, so while bearing the brunt of its attacks with Pokemon excelling in physical Defense, hit back hard with Special attacks to take advantage of its low Special Defense.
