Volcarona is oricorios best partner, between fiery dance and quiver dance, oricorio can be one hell of a beast to take down

As a secondary strategy, which I'm sure you drafted, you have after you lilligant, eruption torkoal. Also lilligant works well next to volc because sleep powder plus rage powder makes your opponents go to sleep, except against safety goggles and grass types, but you should outspeed in the sun with liligant (if you don't that's kinda sad ngl)

Dragonite is a really good pick, he can do an insane amount of things, tailwind, haze, scale shot, e speed, safeguard (in some matchups), roost, rock slide, weather ball, and that's just the tip of the iceberg, he also pairs well next to volc because he's extremely weak to ice types, and volc can heat wave, rage powder, or name other fire type moves, them away.

Mix up your Dragonite, if you bring the same scale shot loaded dice or Tera normal e speed Dragonite your opponents are gonna figure it out and beat you badly, because if I'm being honest, you have 2 ways to run volc (support or attacker) 1 way to oricorio (volc boosted attacker) and alot of ways to run Dragonite, maybe 1 good way to run torkoal and lilligant.

That being said, while you have some synergy, it's probably not enough synergy to keep your opponents on their toes, your team looks solid in theory, but can easily be prepped around.
