Honestly, I don't feel Fur Coat is necessarily OP right now. I fought a team with it a while ago, and they're usually not too hard to kill, specifically due to most of them being a little passive. Although obviously they are a huge obstruction for physical attackers (unless you hit it super effectively or so), they also have to run Furfrou, which is honestly terrible and setup bait most of the time. There may be ways to make it have it carry its weight.. but it's hard.
If anything, Archeops is too good for this metagame. It can't really switch in safely, but if it gets in it almost always ends up destroying something, just like in Gen 5. Besides the obvious core of ArcheKazam, you can also run abilities like Tough Claws and 2HKO nearly everything which dares to switch in. This generation actually benefits it a lot since you dont have to run a Defeatist 'mon when you can just mega-evolve to get rid of the ability.
Akumeoy, in your core, you use Gliscor. How does it function without Poison Heal. I've always seen that as the main draw, and although passing it is nice, I always feel like its a bit lacking if I use it then. Has it pulled its weight? If you want the core to be more balanced you could try Garchomp over it, since it can still deter physical attackers with Flame Body or be immune to wisp with Flash Fire. Alternatively you could just remove Gliscor and get Flame Body on Suicune, which is quite nice since strong physical attackers may not be able to break you because of it.
Finally, when I coded this on Aqua, I revised the banlist a bit. Seeing that this is an outdated metagame, and that many premature bans were made, I felt like it was needed. The current banlist is: Pure Power, Huge Power, Shadow Tag, Arena Trap, Wonder Guard, Contrary, Simple, and Imposter. This opens up a lot of creativity, although of course, abilities can be banned if needed. With Prankster being legal, Thundurus looks like a really good Pokemon on a team, since its already really strong and can pass a great ability. In return it can get stuff like Sheer Force which can easily end up destroying things, because its really strong and has quite good coverage.
Talking about Thundurus, I've used it to pass Prankster to Aurorus. Why?, you may ask. Well Aurorus is one of the few Pokemon which can legally pass an -ate ability, to Pokemon like Dragonite and Lucario. With Prankster Aurorus turns in quite a decent Pokemon, where it may have been useless before. I use it as a suicide lead as its movepool is quite good for a suicide lead. It gets Prankster, Encore, Thunder Wave and Haze, which allow it to nearly always get up Stealth Rock. Encore prevents setting up and Thunder Wave is just generally annoying. Haze is also against setup, but less useful in my opinion. Its Ice-STAB synergizes really well with Thunder Wave as well, since many Electric types (specifically Thundurus) and Ground types hate being hit by an Ice Beam.
