After an Agility, Walking Wake becomes one of the fastest Pokemon in the tier. Its coverage backed up by a Special Attack Booster Energy makes it for a good cleaner and breaker. The other star of the team is 4 attacks Iron Moth with also a Special Attack Booster Energy. Psychic allows it to blow pass Clodsire and Toxapex, and potentially Skeledirge if it gets a SpDef drop. While this team packs a Focus Sash Glimmora, its Modest nature and 3 coverage moves let it be more threatening than usual. Tera Fire + Encore lets Dragonite pray on Will-O-Wisp attempts from Skeledirge and recovery moves from walls such as Garganacl and Toxapex; a Jolly nature lets it outspeed Dragapult after a Dragon Dance and threaten it with Dragon Claw. More details in the RMT.
With Kingambit at around 40% usage this team's Magnezone provides for an interesting answer to the menace, it also helps with Corviknight which is one of the best checks to Dragon Dance Dragonite which is a potential win condition of the team. Eject Pack Great Tusk helps to get up Stealth Rock and act as pivot, both to keep momentum in general, but also as a way to help trap Corviknight. Specs Dragapult is the main speed control of the team, being able to pivot on a potential Kingambit (helping to trap with Magnezone) or dish out damage with powerful Choice Specs attacks. Assault vest Toxapex is very common at the moment and for good reason - it acts as a check to almost every special attacker in the tier. Finally, rounded off by Kingambit which acts as another possible win condition for the team and also a check to Gholdengo.
With its typing and access to Will-O-Wisp and reliable recovery in Morning Sun, Slither Wing acts as a Kingambit and Great Tusk check. Its 8 Speed EVs allow it to outspeed Adamant Kingambit. Cyclizar is the team's hazard control, with enough Speed to outspeed Iron Moth, and SpDef investment backed up by Assault Vest to better pivot around threats like Gholdengo that may cause trouble for balance. Skeledirge opts for Earth Power, which immediately threatens Garganacl and Toxapex.
