Need consistent team for OGL🙏

My first real team since getting into pvp (around the time Steel Wing was buffed i can't recall when) was Skarm, Vig and Swamp. The synergy of Swamp and Skarm was amazing, and oh my old Vig was a delicious ss. However since basically my whole team was nerfed to the ground a couple season ago, i've struggled to find a consistent team to use. Constant switching and mixing trying to find the right combination has got me tired, and with the new season, i figured this will be the time to get a good team- but i'm terrible so teambuilding so i'll put my somewhat viable mons down here:

Shadow:

Machamp, Golurk, Ursaring, Alolan Ninetales, Drapion, Venusaur, Gardevoir, Aslash, Gatr, Abomasnow, Kanto wak, Flygon, Gyarados and Primeape.
