Gliscor

Gliscor is one of the metagame's most defining Pokemon, able to support its team with its bevy of utility options, including acting as one of the tier's premier entry hazard setters and Knock Off users. It can also take over games with its Swords Dance set. Gliscor possesses incredible longevity due to the valuable Poison Heal and a typing that grants it resilience against all entry hazards; when complemented by its solid bulk, this also gives Gliscor the ability to check common faces like Landorus-T and Cinderace and remain unbothered by prevalent walls like Zapdos, Ting-Lu, and Garganacl. Moreover, once Toxic Orb is triggered, it can shrug off status attempts from Pokemon like Moltres, Alomomola, Pecharunt, and Heatran as well as become a reliable Knock Off absorber against the likes of Clefable, Tornadus-T, and opposing Gliscor. All of these attributes combined give it ample opportunities to set up or disrupt the opposition and outlast its offensive checks and entry hazard removers, with its Swords Dance set also capable of exploiting otherwise stalemate situations against foes like Clefable and opposing Gliscor. Thus, Gliscor is a menace against slower playstyles while simultaneously being a valuable asset for them due to its remarkable role compression, defensive utility, and progress-making capability. Unfortunately, its typing also lends it weaknesses to common threats, such as Water-types like Ogerpon-W and Walking Wake, Ice-types like Kyurem, and even other threats like Dragonite, Darkrai, and Great Tusk that frequently run Ice-type coverage to exploit its debilitating weakness. Ogerpon-W, Darkrai, and Great Tusk in particular are Knock Off users that Gliscor subsequently cannot safely absorb the move from. Similarly, the prominence of other entry hazard removers doesn't help Gliscor's case either; Galarian Weezing and its Neutralizing Gas can turn Gliscor's Poison Heal into a liability, Corviknight doesn't mind any of Gliscor's utility moves and can beat even the Swords Dance set one-on-one with Iron Defense, and the likes of Iron Treads and the aforementioned Great Tusk can pressure Gliscor with their Ice-type coverage short-term as well. Thus, Gliscor heavily relies on Terastallization to do most of its jobs effectively, even more notably for Swords Dance variants before it can clean late-game effectively. Gliscor's middling special bulk can also be quite exploitable by wallbreakers like Raging Bolt, Choice Specs Dragapult, and Nasty Plot Gholdengo even while invested. This is especially true against the fast-paced offensive playstyles that stack setup sweepers together, as Gliscor can get overwhelmed easily with the repeated pressure. Gliscor's lack of immediate and reliable recovery, especially as the tier's setup sweepers can easily take advantage of predicted Protect turns by setting up, makes this more of an issue.
