Corsola

Corsola has alright bulk in combination with a large movepool and a great ability in Regenerator; however, it's still outclassed by most other defensive Rock- and Water-types, which generally have either an offensive presence, better stats, a better support movepool, or a combination of the three. Despite its small niche in its reliable recovery, Corsola doesn't have the sheer defenses needed for that to matter. Corsola's poor offensive stats prevent it from being a prominent attacker, mean that it is walled by Grass-types and opposing bulky Water-types, and make it only useful on defensive teams. Corsola's defensive typing can hold it back, as it is weak to common types in the metagame such as Fighting, Grass, Electric, and Ground, and it easily falls prey to coverage moves. Regenerator enables Corsola to become a pivot, although Tangela is better at this job.
