Gorebyss

With access to Shell Smash, Gorebyss is able to serve as a setup sweeper and wallbreaker. Its nice Special Attack, powerful STAB move in Hydro Pump, and average coverage options all help Gorebyss in performing its roles. However, its low Speed largely hinders Gorebyss, making it much easier for Choice Scarf users such as Primeape and Dodrio to revenge kill it, even after a Shell Smash. If Gorebyss has taken enough damage, it can also be revenge killed by priority users such as Skuntank, Kangaskhan, and Hitmonchan. This leads to large competition from Carracosta, which has priority in Aqua Jet to make up for its low Speed, better bulk, Solid Rock, a secondary STAB move in Stone Edge, and the ability to run a mixed set, making it even harder to stop after it sets up a Shell Smash. However, its biggest competition comes from Omastar, which is stronger, faster, and bulkier than Gorebyss and has a useful secondary typing to boot. Between Omastar and Carracosta, there is practically no reason to use Gorebyss in the current meta.
