As one of the main components of the team, this is the team's spinblocker and one of the main pivots. This is also one of my answers to Fighters (Mainly Slither Wing) and having NP + Ghostium allows for more pressure on anything besides Tyranitar (could be changed to Shadow Ball)
The bunny is the breaker of the squad and one of the main abusers of Pecha's easy pivoting, baiting in things like Tyranitar or Tinkaton to let CB Diggersby run wild. This is also a possible revenge killer alongside Booster Jugulis with Quick Attack and still keeping momentum with U-Turn in case there's too many immunities present for Diggersby to risk playing around.
Another pivot that's mostly for the role compression, Cobalion serves as the main Tyranitar switch but also to things like Crobat, Zarude, Ogerpon or M-Absol. This is also a decent wincon with Iron Defense + Body Press which can put enough pressure to get a Fighting resist quick enough and just volt out of there.
Sylveon is a straight forward cleric, allowing me to keep Cobalion healthy, let Pecharunt get hits more comfortably and get Diggersby in vs Electrics without worrying about potential 2HKOs.
Jugulis is the cleaner of the team once Diggersby and Pecharunt have dealt enough damage to the opposing team while also being an emergency check to things like Nihilego, Scarf Mienshao, Zeraora, or Zarude.
Ogerpon was a quick last since i wanted a lot more utility (Knock Off, U-Turn and Spikes mainly) while also being a Ground resist for Sandy Shocks, opposing Diggersby and Krookodile.
