Piloswine's strong matchups against the tier's other dominant entry hazard setters, such as Tinkatuff and Koffing, and the tier's premier Defogger, Vullaby, allow it to excel as a highly effective Stealth Rock setter. As a wallbreaker, its unresisted STAB combination is extremely threatening to unprepared teams and those that have been weakened by Knock Off, hazards, or other residual damage. High Horsepower allows Piloswine to work effectively even in Grassy Terrain, but Earthquake is also a viable alternative due to its extra power and accuracy. Ice Shard allows Piloswine to pick off weakened threats like Girafarig and Fraxure.
Piloswine is a strong fit for most archetypes, and it's especially effective on bulky offense and balance teams. Drakloak is a good teammate for Piloswine; its spinblocking ability, which allows it to handle Quaxwell, complements Piloswine's Stealth Rock setting perfectly. In addition, Drakloak can spread status to support Piloswine's wallbreaking or work in tandem with it to dismantle the opposing team through pivoting. Frogadier is also a superb partner, forming an entry hazard-stacking core with Piloswine; moreover, it provides pivoting support to Piloswine, creating valuable entry opportunities. In a similar vein, Koffing sets Toxic Spikes to maximize hazard pressure; it also acts as a great switch-in to many foes that Piloswine is weak to, handling Grass-types like Thwackey and Servine and absorbing Fighting-type moves from threats like Raboot, Monferno, and Pignite. In general, wallbreakers and cleaners appreciate Piloswine's Stealth Rock support and offensive pressure; Thwackey, Girafarig, Fraxure, and Raboot synergize extremely well with Piloswine, working hand in hand with it to dismantle defensive cores, which may include Pokemon like Dunsparce, Ivysaur, Quaxwell, and Koffing. Thwackey, in particular, is an excellent teammate for Piloswine, dealing with pesky Water-types that check Piloswine, namely Quaxwell, Wartortle, and Frogadier. Thwackey also offers invaluable Knock Off, pivoting, and passive recovery support, bolstering Piloswine's wallbreaking prowess and longevity. In return, Piloswine deals with foes that can prove to be problematic for Thwackey, such as Koffing, Vullaby, and Tinkatuff. Piloswine appreciates Knock Off support a ton; thus, Knock Off users such as Monferno, Pignite, and Ivysaur make amazing teammates, pairing nicely with Piloswine and amplifying its offensive pressure, even allowing it to reach thresholds like 2HKOing maximum Defense Quaxwell that has lost its Eviolite with minimum chip damage. Defensively, Quaxwell is a remarkable teammate, providing Rapid Spin support to ensure Piloswine's side of the field is free of hazards, thus maximizing hazard pressure on the opposing team. Quaxwell also acts as a switch-in to multiple Pokemon that Piloswine can struggle against, especially if it's chipped or if its Eviolite has been removed by Knock Off, such as Frogadier, Pignite, Monferno, and Raboot; in exchange, Piloswine can deal with foes that Quaxwell is weak to, like Drakloak, Fraxure, and Girafarig. Wartortle is also a good teammate in this regard, though it has less longevity, which is a fair trade for the added offensive pressure. Ivysaur defensively takes care of Grass- and Water-types like Thwackey and Quaxwell for Piloswine, while Piloswine takes care of threats like Girafarig and Tinkatuff.
