Cloyster HP: 50 Atk: 95 Def: 180 SpA: 85 SpD: 45 Spe: 70 Singles Sets Cloyster @ Focus Sash 4 HP / 252 Atk / 252 Spe nature: Jolly / Naive ability: Skill Link - Shell Smash - Icicle Spear - Rock Blast - Razor Shell / Hydro Pump Cloyster makes for an excellent boosting attacker in GBU singles, becoming very difficult to stop after a Shell Smash. With rain support, it's nigh unstoppable without priority, and Focus Sash allows Cloyster to always survive a hit. Shell Smash's Speed boost means Cloyster outspeeds practically everything in common usage. Icicle Spear, Rock Blast, and Razor Shell have perfect coverage together. Hydro Pump allows Cloyster to get past physically bulky Pokemon such as Skarmory, but its accuracy is off-putting. If using Hydro Pump, use a Naive nature.
