I have been meaning to post for a while now but have always been either too busy or just forgot. So, sorry sos but here’s my submission

So the team’s concept is trying to build around
specs emp + 4a luc, both of which appreciates spikes support so I choose to go with an offensive skarmory lead. Normally I’d go the suicide route and go with brave bird instead of roost, but I have blissey on this team and skarm’s defensive utility works in tandem with bliss well, so it may be useful to keep skarm around for a defensive core late game. Taunt + roost itself can force progress on certain mons like scizor regardless.
So, why specs emp + 4a luc? They form a scary offensive core against stall, and weaken each other’s checks well. Empoleon can potentially bait in and weaken water types such as suicune and gyarados, both of which are annoying for luc to handle, as well as latias and even defensive rachi. In turn, jolly luc baits in rotom and gliscor, which would otherwise be offensive checks and obstacle to a late game emp cleanup. A lucario lacking swords dance also makes skarmory a nuisance, and nothing punishes a skarm switch in quite like a specs empoleon double. Although, this also makes the prospect of facing spikes quite unsavoury, especially since blissey is also in this team. The user should take care to not let opposing skarm have an opportunity if possible.
Gyarados is one of the few mons that can stand up to either of these two, and thus your own
stone edge gyarados is a great way to take advantage of that. It also handles infernape well mostly and makes the team less flimsy against heatran and flygon especially. It can also answer gengar in a pinch.
Of course, giving all these defensive duties to gyara is not feasible to say the least and
Blissey rounds the team out well, being able to absorb specs lati draco without having to sacrifice health on emp, as well as answer things like mixgon and calm mind jirachi. Ice beam makes it a valid answer against rt rotom and especially gengar which are both otherwise hard to handle for the team. Alternatively double rocks can be used here if you’re not confident in skarm’s ability to set up rocks securely.
Finally, scarf rotom is there to provide spinblocking opportunities and a modest nature is run there for more pressure against things like zapdos and opposing rachi, and more importantly the extra defense allows it to have a better chance of taking an outrage from scarf flygon after 2 rocks switchins.
Side note: 4 attacks lucario is an underappreciated set, mostly because people really would only look for lucario because of how threatening it is with sd. However, swords dance is quite hard to click in a given game and being able to hit both rotom and gliscor (on the switch) is a very valuable trait especially since people usually only expect one of these coverage attacks. It’s worth noting that scarf lucario is still a great set despite the mechanics change, as it is the scarfer with the most raw power out of anyone else (other than heracross), especially if you’re running adamant which you can afford to, achieving feats such as 2hkoing offensive swampert switchin.
