I'll keep the explanations short and keep the hyper offense style your team has
First, if you wanna use Hawlucha, you need to find a way to get rid of Zapdos. Garchomp does this very well and is a reliable stealth rocker and wallbreaker. Blaziken is too match up dependent to use and Slowbro is getting more and more common
For Latios, just use specs set. Trick to ruin any walls that try to stop you and use psyshock so you don't get walled by Blissey. You can replace mystical fire with aura sphere if you are worried about Heatran
Never use iron head on Cinderace. Steel is not a good offensive typing atm as the only one you're gonna hit is Clefable, which gets destroyed by gunk shot so use u turn instead to bring in a teammate safely
Use choice band Crawdaunt. This thing is hell to switch into if you are unprepared and has been starting to pick up usage as far as I've noticed. It should be obvious why and this mon is a backup cleaner and your Slowbro killer, a pokemon that irritates Hawlucha and Garchomp
Use Tapu Koko over Kyurem. Kyurem is a powerful wallbreaker but it has a lot of issues, chief among them is stealth rock. It's best used under hail where it can mindlessly spam blizzard but under hyper offense, it is far too easy to lose momentum with wrong prediction especially since ho teams only have a few turns to spare. Latios doesn't exactly have that problem as trick can ruin nearly any switch in that isn't Galarian Slowking. You could go for life orb but again, stealth rock. Tapu Koko gives you the ability to stop defogs and hazards while providing your team with screens
Use electric seed Hawlucha. Never use a switch move on an unburden pokemon. That would contradict on why you are even using an unburden mon in the first place. You can replace stone edge with taunt to prevent haze attempts since Garchomp already kills Zapdos
