Barbaracle

Barbaracle has carved itself a niche in the UnderUsed metagame as a potent Shell Smash sweeper due to its access to Liquidation and ability to viably run Rockium Z. Most teams are easily swept due to lack of preparation for Barbaracle, as they usually only have a couple decent checks for it and are more often than not unable to prevent it from gaining a good setup opportunity thanks to its great Defense and strong offensive typing. Barbaracle is also one of the tier's better stallbreakers, thanks to its ability to be a boosting Pokemon that can break past most of stall's typical answers like Quagsire. However, while Barbaracle is generally effective against most playstyles, it tends to struggle against most matchups where the opponent has one or two strong checks to Barbaracle and thus can dissuade it from ever setting up a Shell Smash. Furthermore, Barbaracle is a one-trick pony and requires its teammates to cater to it in order to function successfully in the tier. This reliance on being built around as well as its reliance on Shell Smash in order to become a potent threat makes Barbaracle a rather mediocre option when compared to other setup sweepers with more overall utility like Scizor.
