The goal of the team is to pivot around with the defensive core of Rotom/Amoongus/Arcanine, while spreading damage with the offensive mons, setting up for an endgame with any Gholdengo/Dragonite/Garganacl. The team works especially well into other bulky teams, but has to be careful into sun HO, although I've found it manageable.
Very strong and fast attacker that pairs well with Garganacl and is great at spreading damage. Trick also does a great job a crippling all the slower setup sweepers or defensive mons running around the meta. Also deals with opposing Garganacl's well. Tera Steel is the only way to garuntee an ohko on uninvested Flutter Main, and the extra damage in general has outweighed the utility of a more defensive tera so far.
Classic CB Dragonite Extreme Speed bot. Speed is to outrun uninvested Dondozo with the Commander boost, and generally speed creep other Dragonites, so they can be adjusted if you don't think its necessary.
Garganacl's main job is to sit on the board, eat hits, and spread damage with salt cure. Spdef to take Fire hits for Gholdengo better. Tera ghost for the mirror, although a tera to better deal with Flutter/Chi-Yu pairs might be useful as well.
Rotom-Wash is a very solid defensive pivot, with enough bulk to live hits and spread burns. The ev spread outspeeds Brute Bonnet, lives 2 untera'd Dragonite Espeeds, with the rest dumped into special bulk.
Covert Cloak Amoonguss is great, ignores flinch to more reliably Spore things, and ignores Salt Cure damage so opposing Garganacl can't touch it.
AV Arcanine was chosen to generally sponge special hits better, and deal more damage to opposing Amoongus, which can be problamatic at times. Rotom fills the role of spreading burns so Arcanine doesn't feel the need to and can focus more on doing immediate damage. Tera Grass is a nice option to catch people off-guard and deal more damage to bulky grounds, as Rotom doesn't always cover it.
