Arcanine

Access to the powerful priority of Extreme Speed, the simultaneous offensive and defensive boosting of Curse, and the healing of Morning Sun solidifies Arcanine as a sweeper to be respected, capable of taking advantage of common passive foes such as Bronzong, Sylveon, Amoonguss, Klefki, and Wo-Chien as well as KOing common offensive threats like Flygon, Munkidori, and Flamigo. Additionally, Arcanine complements many sweepers such as Alolan Ninetales, Flygon, Oricorio-P, and Diancie, making it slot in easily on tons of offensive teams. Arcanine also has use throughout the course of a game, as with Intimidate, it can slow down opposing wallbreakers and sweepers, easing the burden on its teammates. However, if Arcanine wants to get past bulky Water-types like Vaporeon and Swampert, then it's forced to Terastallize and, consequently, risk a Scald burn from Vaporeon. On top of that, Arcanine often finds itself stuck between Stealth Rock and a hard place by having to choose between Leftovers + Crunch and Heavy-Duty Boots + Morning Sun; the former combination provides Arcanine coverage to nail Basculegion-M and Chandelure at the risk of being chipped heavily by entry hazards, while the latter offers reliable healing and more chances to set up during a game at the cost of being hard walled by the aforementioned Ghost-types.
