The team started out with SS Gorebyss, which basically only has Choice Scarf users like Rotom-F and Sawsbuck as counterplay once it has powered up via Shell Smash. This team seeks to give Gorebyss the support it requires in setting up, so I stacked it with Memento, paralysis, sleep, and dual screen users. Gorebyss is also stopped by Kadabra if its Focus Sash hasn't been broken yet, so I gave the team a defensive switch-in to beat Kadabra in Probopass (unless Kadabra uses HP Fighting or Ground on the switch), and another setup sweeper in Linoone to force Kadabra in, break its Sash, and open up the way for Gorebyss to sweep past Kadabra late-game.
Jumpluff was an obvious addition to the team for its type synergy with other members, ability to create setup opportunities via Sleep Powder and Memento, and because it's faster than Kadabra and is therefore able to pivot on and break Kadabra's Focus Sash. Jumpluff also helps Linoone set up in the same manner, which means in most battles, either Gorebyss or Linoone will be sweeping your opponent's team. Encore is an option over Memento, and beats annoying things like Duosion or Vigoroth who try to set up on you. You may have noticed that Jumpluff is using Chlorophyll over Infiltrator - this makes it so your team always has a check to slower Chlorophyll boosted Pokemon like Exeggutor, Sawsbuck, and Leafeon so that you don't lose to sun teams. Gorebyss on the other end is running Swift Swim, which also gives you an answer to rain teams.
Next, I wanted dual screens and paralysis to help both Linoone and Gorebyss set up easily when under fire, so Meowstic with Prankster was an easy fit. It is EV'd offensively, and lets you outspeed and OHKO Monferno after SR damage with Psychic so that some of the offensive pressure which sometimes prevents Linoone from setting up is relieved to an extent. Meowstic has nice defensive synergy with Probopass and Linoone and provides them with a degree of protection from Fighting-type attacks.
I used Probopass as my SR user here; while I could have used Metang to Pursuit-trap Kadabra for the team, I felt that removing Steel-types for Linoone via Magnet Pull was just as important. Probopass also provides a better switch-in into Dodrio, and a slow Volt Switch which helps get in Linoone or Gorebyss safely without needing to take a hit in order to set up.
And finally, to round out the team, I used Zebstrika here for an electric immunity, an offensive check to Floatzel and Jumpluff (which would be big threats otherwise), to provide enough Speed to be able to pivot on Kadabra's Sash and break it, and to beat defensive answers to Linoone like Tangela, Klang, Gourgeist, etc. via Overheat.
Overall, the team has double setup and 2 Pokemon faster than Kadabra, which make it so Kadabra is more likely to use up its Sash so either Gorebyss or Linoone can sweep late-game. Linoone can be ran faster with a different EV spread to accommodate for fast Stallbreaker Misdreavus, but doing so can detract from its bulk and is therefore optional. This team also has 1 Chlorophyll user (Jumpluff) and 1 Swift Swim user (Gorebyss), so that you have options to beat each weather archetype. Hope you enjoy the team!
