Carracosta

Balanced attacking stats, decent STAB coverage, access to Shell Smash, and two usable abilities in Sturdy and Solid Rock turn Carracosta into a potent sweeper. With these abilities, a stellar base 133 Defense stat, and great physical coverage, Carracosta easily sets itself apart from Omastar as a Shell Smash user and Kabutops as a Choice Band user. It's not all good news for Carracosta, though; its vulnerability to the common Fighting-, Ground-, Electric-, and Grass-type attacks hampers its ability to sweep completely, even with Solid Rock. The fossil is also painfully slow; even though Shell Smash helps remedy this to an extent, he is still easily outsped. Despite these drawbacks, Carracosta is still a great Pokemon and is a good choice for any team that needs a powerful and reliable sweeper.
