1) Standard Pelipper, gets rain up for the sweepers and the Ferrothorn, it has hurricane to damage Tangrowth and Tapu Bulu (grass types in general)
2) Gorebyss, the main star of the team. Swift Swim boosts its speed to very high levels, and with Shell Smash, it makes it even faster and more more ''powerful''. It's able Shell Smash on choice locked mons and defensive ones stuff like Pex, Tran, Mew, etc.. and even on predicted switch-outs. Speaking of pex, you beat it thanks to the Psychium Z Psychic and the Psychic Terrain (you always ko it in terrain, no matter if you're boosted). You also do ohko Mega-Venusaur with this set in terrain or at +2. It also gives you an all around nuke vs. Fini, Tangrowth, Kyurem-B, ... KOing them at +2 with the modest nature thanks to the terrain boost. All what you have to weaken for Gorebyss is basically opposing Ferrothorns and Celesteela, and like get 15% off of Gren, which is helped by the spikes and the stealth rocks. But all around this mon works pretty well and does its job of being a win con surprisingly well. If you can keep the psychic terrain even longer, you can even prevent priority from hitting it, which will guarantee the sweep!
3) Ferrothorn: how to make a rain team without Ferrothorn ? The rain helps it take on most Lele, Zapdos, opposing rain etc... Spikes helps Gorebyss get some KOes, Knock off helps a lot vs. Tangrowth, Celesteela and Ferrothorn and finally Gyroball, which is to hit faster threats like Koko and Serperior. Lacking Power Whip is kinda annoying vs. Fini, but you can play around that. Obviously, you have to be aware of the fact that you are a complete setup fodder for opposing Kartana. It's also your only answer to Ash gren, which is the main threat to this team, beside Magearna/Garchomp (it's rain tho, so it's not really a surprise, but still)
4) Tapu Lele, another offensive mon that pairs very well with Gorebyss, as Lele widdles down Gorebyss checks pretty efficiently! It's the mon that I am the less sure of the set, but it has been working OK in my testing. Taunt helps you vs. Trick Room, which the team is terribly weak to. Also can block Celesteela's Leech Seed, Ferrothorn's Spikes, Zygarde's setup etc... The combination of stabs + Nature's Madness can really put in the work early game, getting half-health damage on Ferrothorn, Celesteela, and denting Landorus, Heatran and the Tapus. I've a tendancy to lead with it a lot, because most people expect choice-locked Lele on a team with such a weakness to DD Dragonite, SD Chomp, SD Pinsir, ... and it can really pressure Koko leads, that try to catch Pelipper. It can also bluff Scarf to a certain extend too (watch out for the terrain activation). Finally Lefties helps you get back HP, while also beating Mew 1 on 1 thanks to Taunt. You can make it Terrain Extender if you want, and maybe slap Focus Blast over Nature's Madness. I've tried both moves and I've been fine with each one of them (even taunt can be replaced, but i liked it lot on this team)
5) Zapdos is really important to the team, as it is one of your few answers to Kartana, Celesteela, Hawlucha, ... It's your hazard countermesure, and it can really beatdown certain teams that really have nothing for it. Thunder doesn't miss in rain, but I like Discharge more cause it's more reliabe. The only bad thing is that you don't have Heat Wave, but its power is halved in rain anyways. But that makes mons like Bulu really though to beat, so you have to be causious facing it. It's also you main Lando switch-in (try to scout for rockium with Swampert if necessary).
6) Rain = Swampert, basic stuff. It's the one rocker in the team. Aqua Tail 2 hit Koes Celesteela, and does more damage in general to Mew and Clefable. It's a really good win con and it's really good at cleaning what Gorebyss has already powered through.

So there's the team! Lmk what you'd change in it, i'm very curious. Hope you'll have fun if you use it! Appreciate the content, keep it up my man :]
