Shellder is technically a pre-evolution of Cloyster, but it holds its own in formats where Eviolite is allowed. Only weak to Electric and Grass. Flexible enough to run physical or special sets. Been around since Gen 1.
Shellder's spread isn't flashy. Defense leads, Sp. Def trails, 1 stats clear the bar. Common in the wild and worth 1 Defense EV, on a slow 1.25M XP grind.
It is encased in a shell that is harder than diamond. Inside, however, it is surprisingly tender.
Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.
Shellder Weakness
GoodType-wise, Shellder takes extra damage from Electric and Grass. It resists 4 types, giving it decent defensive coverage. Shellder's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
