Hey jam, here's a team featuring Toxtricity in Ou, https://pokepast.es/9294378964442dfa - Premise would be essentially being able to bait bulky waters and etc with protective pads urshifu and then giving Toxtricity and regieleki opportunities to wreak havoc. Toxtricity can easily clear the way for regieleki by baiting in grounds and etc and allows Eleki to go in easily.
Or tho the team features 5 uu mons it's still really good! SpDef Scizor for all the ladder kids spamming Kyurem and Tapu Lele, Cb Terrakion to 2HKO even max defense Corviknight and Toxapex with Eq and CC respectively and last but definitely not least you got tangrowth for Rillaboom and Kartana! https://pokepast.es/caeef506dc897559
Built a team around mons that are better now that Ace and Mag are banned. Kyurem is paired w Lele to overwhelm, with Blaziken to pressure walls or sweep. Vaporeon was also a fun/niche pick, though Blissey would likely be a bit better.
Specs Magearna team: https://pokepast.es/68ae86f50ffa1f55
Paired this thing w/Heatran to trap Pex and Latios to lure Heatran,but Mag handles Tran on her own
You can swap Fini for Teleport Slowbro to bring Mag in, but I prefer Defog.
Bisharp was the latest addition and I´m still not sure about it, need some way to punish Specs Dragapult which outspeeds the entire team
Feel Free to Make Any Changes!
