In-Depth Analysis
Cloyster's 525 base stat total marks it as a balanced Pokémon with a flexible stat spread. Defense (180) carries most matchups, but a low Special Defense stat of 45 means careful positioning matters.
Defensively, the Water, Ice combination gives Cloyster 2 resistances and 4 weaknesses to plan around. Notably, it carries no 4× weaknesses, which makes it harder to punish. Offensively it pressures 6 types with super-effective STAB coverage.
A catch rate of 60 puts Cloyster in the moderate range — a few Great Balls usually get the job done. It levels on the Slow experience curve. Defeating it grants Defense +2 EVs, which is worth remembering when EV-training your own team.
