BDSP Cloyster Best Moveset
Dropped from A-tier but AbilitySkill Link guaranteeing 5 hits on multi-strike moves combined with MoveShell Smash for +2 Attack, Sp. Atk, and Speed in one turn gives the moveset an explosive setup path it lacked in the original Gen 4. 180 Defense absorbs physical hits during setup. B-tier because 50/45 HP and Sp. Def fold to special attacks.
