Duosion

With the combination of reliable recovery, Eviolite, and, most notably, Magic Guard, Duosion makes for a prime option as a wall and bulky setup sweeper. Unlike many other setup sweepers, Duosion can check many walls such as Bronzor, Maractus, and Tentacool and use them as setup fodder without fear of moves like Toxic and Leech Seed. However, Duosion has to watch out for Knock Off, as it relies heavily on its Eviolite to tank hits while setting up, especially if not running Acid Armor. Duosion can also do significant damage without the need to set up with its naturally high Special Attack, making it both an offensive and defensive threat. The immunity to hazards allows Duosion to switch in and take hits more safely, which is very valuable due to the lack of hazard removal in the tier. However, Duosion faces large competition with Beheeyem, which can serve as a bulky setup sweeper without having to rely on Eviolite for bulk, allowing it to hold Leftovers or expand its versatility on offensive sets with items like Choice Specs and Life Orb. Duosion also suffers from four-moveslot syndrome, making it choose between a worse matchup against physical wallbreakers like Stoutland and Marowak or being hard-walled by Dark-types like Shiftry and Zweilous.
