-I'll assume Fortress' last move is Toxic Spikes? Usually, with so many flying and steel types around, i prefer to go for rapid spin to get rid of enemy hazards instead. -With Lucario, the problem is that Aura Sphere is a special move while the rest are physical, so I'd change it for Close Combat. Also, chosing Bulk Up over Swords Dance is a bit questionable, and rather than Poison Jab maybe something that does better against Lucario's main weaknesses.
-Jolteon should run an all special attack set in my opinion, with Volt Switch, Thunder/Tbolt, and then a choice of coverage moves like Shadow Ball and Signal Beam.
-Metagross. I would change out Bulldoze for Earthquake, Confusion for Zen Headbutt and maybe Aerial Ace for Meteor Mash or a more powerful move like Hammer Arm.
-Gliscor best runs defensive sets with the toxic sub stall
-Tyranitar usually has stealth rocks, but I guess with Fortress it isn't critical. Crunch > Bite. I'd scrap Bulldoze for Dragon Dance and get Pursuit or Stone Edge over Blizzard.
Those would be my fixes to make it more of a competitive team
