CWaterIceAttackerHardM-B legal

Cloyster is a Water/Ice-type attacker valued for multi-hit cleanup after one setup turn.

Is Cloyster good in Pokémon Champions?

Cloyster is an editorial C Tier Pokémon whose main jobs are attacker. The short reason to consider it is multi-hit cleanup after one setup turn. That strength gives the team a clear way to create progress, but it does not make Cloyster automatic on every roster. Its typing, item, move slots, and partners must all support the same plan.

For Regulation Set M-B, Cloyster is marked legal in our planning database. Use that flag for quick filtering, then confirm the exact form, item, and current notice inside the game before queueing. The tier is an editorial judgment based on flexibility, beginner usefulness, role value, and familiar competitive trends rather than official usage statistics.

This set is designed to make Cloyster's job readable from team preview. Icicle Spear is the first move to understand because it usually represents the set’s most direct way to apply pressure. Rock Blast complements that option with a second target profile, while Shell Smash and Protect supply coverage, priority, setup, protection, or disruption depending on the matchup.

Best moves for Cloyster

Do not choose four attacks only because they have the largest damage numbers. A useful Pokémon Champions moveset gives the player at least one safe or repeatable decision. On this build, the four recommended moves are Icicle Spear, Rock Blast, Shell Smash, Protect. Before replacing one, ask whether the team already covers the targets that move is meant to hit and whether another teammate can provide the lost utility.

Protect-style moves become more valuable in Doubles because they can waste an opponent’s focused attack while a partner changes the board. Priority is valuable when speed control expires. Spread moves pressure both opposing slots but can be reduced by defensive tools. Status and support moves may deal no immediate damage, yet they often create the turn that lets the primary attacker secure a knockout.

Best item and ability

White Herb is the recommended item because it reinforces the attacker plan without asking the other five team members to change their jobs. Item Clause means a complete roster cannot casually repeat the same important item, so compare this recommendation with the needs of your other core Pokémon. If another member depends on it more, test a legal alternative rather than copying the build blindly.

Skill Link creates a distinct interaction to plan around. The ability is most useful when you know whether it activates automatically, responds to an opponent, changes damage, redirects an attack, or alters field conditions. At team preview, identify which opposing Pokémon can ignore or exploit that interaction. This prevents a familiar set from becoming predictable.

What It Does Well

Strengths

  • multi-hit cleanup after one setup turn
  • Skill Link creates a distinct team-building angle
  • Water and Ice coverage supports its primary role

Cloyster is easiest to use when the lead immediately supports one of these strengths. Avoid spending early turns on actions that do not advance its main role.

Counterplay

Weaknesses and counters

  • special attacks and setup denial
  • Requires teammates that cover its most common type matchups
Team Support

Best teammates for Cloyster

Partners should cover special attacks and setup denial while helping Cloyster perform its attacker role.

A partner is not automatically good just because it resists one attack. Look for shared tempo: Fake Out can create a safe action, redirection can protect a fragile attacker, speed control can change move order, and a defensive pivot can preserve the team’s main win condition. Test the suggested partners one at a time so you can identify which interaction actually improves difficult matchups.

Beginner tips for Cloyster

Cloyster is marked as a practice-first choice because timing and positioning matter more than they appear from the moveset alone. Start by learning one reliable lead and one safe switch. During review, ask whether Cloyster entered the field at a moment when it could use Icicle Spear or support its partner without immediately being forced out.

Do not measure value only by knockouts. A support can win a game by changing speed, redirecting one attack, or weakening a physical threat. A tank can create value by forcing the opponent to spend two turns on it. An attacker can create value by making Protect or a defensive switch predictable. Track whether Cloyster helped the team control decisions, not just how much health it removed.

Regulation Set M-B notes

M-B team preview gives you ninety seconds to select the participating Pokémon. When Cloyster appears in your six, identify its best targets and the opposing answers before choosing the final group. In Doubles, build a group of four that contains a lead plan, a defensive switch, enough damage to close the battle, and a secondary speed option. In Singles, preserve coverage for the three opponents most likely to be selected.

Legality can depend on more than the species name. Forms, Mega Stones, moves, items, and updates can affect the final check. ChampionsDex’s legality label is maintained for planning and filtering, but the current in-game notice always wins. Return to the Regulation Set M-B Guide when the season changes or a saved build stops passing validation.
