Shellos

Shellos holds a unique niche over common bulky Water-types thanks to Sticky Hold, which allows it to permanently hold on to its Eviolite. It has a decent movepool that grants it access to Scald, Earth Power, Yawn, Clear Smog, and, most importantly, Recover. Shellos also has a solid defensive Water typing. However, said typing also means that Shellos will be vulnerable to common Electric- and Grass-types such as Chinchou, Magnemite, and Foongus. All of Shellos's base stats bar HP are relatively mediocre, meaning it has middling bulk, which allows powerful wallbreakers such as Abra, Snivy, and Rufflet to significantly weaken it, and Shellos's low offensive stats cause it to drain momentum while potentially being used as setup bait.
