Spore is stopped by Safety Goggles and Baton Pass by Haze/Spectral Thief/Heart Swap. Your team looks ridiculously vulnerable to anti-set-up. A good Unaware Gyarados could Spectral Thief any of your set-up, except Xtwo, and then counter-sweep you. And that's just for starters. Prankster Haze Registeel checks your whole team (and Destiny Bonds Xtwo.) Speed/para support Light Ball Imposter Pikachu likely counter-sweeps your team if you don't have Imprison up. Aside from anti-set-up, you also pretty much lose to Simple Sash Smash and shuffle-heavy teams.
-Beyond that, looking at your sets in a vacuum and starting with Deo-S, screens are bad in the meta due to how long matches can last and the ubiquity of Defog. Almost every competent team will be able to remove your screens without having even built to counter screens. Deo-S' set needs to be changed entirely.
-Gyarados is more or less fine.
-Gengar probably wants Mold Breaker more than Dazzling. Substitute protects you from most priority that Dazzling would stop. Though Sub still may or may not be the best answer.
-Imposter is Imposter, the set is fine.
-On Xtwo, Accelrock is just bad. I mean, here's a target you'd want to hit...
+6 252 Atk Mewtwo-Mega-X Accelerock vs. 252 HP / 252 Def Rayquaza-Mega: 368-434 (88.8 - 104.8%) -- 31.3% chance to OHKO
...which you don't even guarantee a KO on. Neutrally hit Pokemon are just going to scoff. Besides, you have Unburden, you don't really need the priority.
-Genesect is kinda just bad, since it has really bad STAB coverage and a crummy speed tier. I'd just drop it entirely. Besides, its coverage is fairly questionable, especially since Giratina, one of the most common walls, kinda just shrugs at it.
Now, I'm limited on time, so there's likely more that needs covering here. Especially team synergy and stuff. But, between my lack of time atm and me not being great at hyper offense anyway, I can't really say much other than seriously consider some Pokemon/sets that don't need to set-up to attack and consider some bulky offensive Pokemon who can get going without playing "do or die" every time they try to set-up. You also have no way to get anyone in safely outside of revenge or a good prediction, so you may look into some pivots as well.
