I don't post here very often, but I thought I might give this a shot. I'm also not very good at explaining things, but I'll do my best. The structure here is nothing crazy at all; very simplistic. The idea behind it was that SD Gliscor has a good niche in able to deal with opposing HO, in that it prevents free setup from Gyara and Dnite. Consequently, even with no HP investment, it doesn't get revenge killed by Flygon from above ~50%; hence, the Azelf HO team that has a mon that's good against opposing HO, who's also a HO mon. This Gliscor aims to hit the big 3 (thunder fang for Gyara, ice fang for Dnite and eq for Tar), while being a setup mon itself. It's an extremely aggressive team, which utilises Yache Berry to get a change to setup on things like tar. Mixed Nite allows you to not be completely defenseless against physical Skarm. Wacan Gyara ensures that you live a tbolt, or thunder punch from scarf gon, to give you that extra setup opportunity, or damage in. Chople on DDtar gives you some insurance vs Gengar whist Crunch is there for a more reliable STAB + defense drops (if you're lucky). Bulky Azelf is a fairly reliable lead to ensure rocks are up, and one of the guys comes in safely, when coming across things like meta leads. Tar/Gyara/Nite + Glisc help to offensively overwhelm the opponent's team to ensure a sweep with SubPetaya Emp, one of the most devastating endgame cleaners in the tier. The good thing about this team is that win cons are quite flexible, as you also have DDTar, DDGyara and SD Glisc to clean things up for you.
As mentioned before, this team is very aggressive; you will either win or lose on the spot, so you gotta go hard or go home and make smart doubles/maneuvers to get in your guys safely. DDtar with aqua tail, though not that common, makes things a bit more annoying for Glisc for setup. Defensive Zapdos is also quite frustrating to deal with, though stone edge could replace crunch on Tar to rectify the issue, at the expense of risking a stone edge miss.
