This is a cool set, but I think your strategy is flawed. Very few teams overall won't be running some type of fairy, and immediately subbing is basically signalling that you're a setup set before you actually do anything; the only thing you're actually bluffing is Belly Drum. Special over Physical may catch your opponent off-guard enough to deal with something like a Corviknight, but if a team has a Fini, a Clef, or even a Lele or a Synthesis Bulu, you've just put your Kommo-O at 40% and wasted your one-time setup for very little gain, because with Dragon/Fighting coverage you can't touch them. Even outside of fairies, there's still strong checks. Toxapex can come in on predicted Aura Spheres and press Haze, Blissey and SpDef Corviknight can come in on predicting Clanging Scales and break the sub, and G-Slowking will eat anything you throw at it and press Future Sight.I've been having a lot of fun using this set-up Special Kommo-o set, especially after Magearna's recent ban.

It's typically my lead, mostly as a fake Stealth Rock setter. Sub 1st turn, then immediately Clangorous Soulblaze to boost all of its stats while Throat Spray would activate and give it +1 more SpA.
It has problems with Fini tho, but I've been seeing less of it lately.
204 Speed investment + Timid makes it able to outspeed Timid Dragapult after a Clangorous Soulblaze.
Also, I'm somewhat confused about the EV spread - when neglecting SpA this much, you miss out on certain 2HKOs that end up pretty important (Tapu Koko, Corviknight, Blissey), and the bulk you get from HP is really not that important considering you're essentially starting the battle at 42% in a best case scenario. You only need 88 HP evs to stop Grassy Glide from breaking the sub, and I'm struggling to think of much else that might be an issue there.
The optimal way to use a one-time sweeping set like this is to gradually chip away at opponent's checks using strong breakers and hazard support, pressure them out of healing, and generally find ways to turn its 3hkos into 2hkos, and 2hkos into Ohkos. Leading with it robs you of this opportunity; if you try to turn 1 sweep before doing anything, you'll find it hard to break past anything aside from lucky crits; even at a basic level, all you need is one bit of stealth rock chip to turn Corviknight from a roll into a clean 2hko. The benefit of something like Kommo-o over a stronger sweeper like Hawlucha is that people don't always expect it to be setup; and this can often lead to people letting checks get damaged thinking that it's defensive. Leading with this gives your opponent just a single turn of thinking that; saving it for the end can give you the whole game to take advantage of that.
tl;dr stop trying to turn 1 sweep
