Carracosta

Carracosta finds its place in the PU metagame as a potent setup sweeper and wallbreaker thanks to its access to Shell Smash, a STAB priority move, respectable offensive presence, and a great physically defensive presence. Its typing, physical bulk, and ability Solid Rock grant Carracosta multiple setup opportunities in front of Normal- and Flying-types in the tier, and its good attacking stats allows it to run a mixed set able to break through a big portion of the tier. Its access to Aqua Jet gives it a niche over its main competition as a Shell Smash user in the tier, Omastar, since it allows Carracosta to break through common Choice Scarf users in the tier such as Primeape and Dodrio as well as naturally faster Pokemon, meaning that it's harder to revenge kill than its competition. Despite this, a low Special Defense stat and a terrible Speed stat mean that Carracosta is often forced out by many common special attackers such as Victreebel, Alolan Raichu, and Ludicolo if it hasn't managed to set up. This problem is further accentuated by its 4x weakness to Grass and weakness to common types such as Electric and Fighting from the likes of Abomasnow, Eelektross, and Gurdurr. Carracosta also struggles to break through physical walls such as Tangela and Ferroseed if it lacks the coverage move to hit them for maximum damage. Furthermove, Carracosta still suffers competition from Shell Smash Omastar, which outclasses it in power and Speed.
