Sub Volcanion is really solid in OU. Water-Fire-Ground coverage beats the super common Ferro/Lando/Pex cores, as well as threatens Heatran, Celesteela and Bulu.
This OU team is pretty offensive and is my personal favorite to ladder with, enjoy.
I have a Mamoswine team that I got to 1682 with. It uses Mega Latios, which is a pokemon I rarely see in your videos. Maybe you can try out the Mamo and Mega-Latios synergy? #MamoTTT
An OU team using some less popular OU mons. Tornadus can U turn on switch ins and get momentum with Diancie, Tyranitar or Keldeo. Really fun playstyle and a generally kooky team.
https://pastebin.com/XP60evYw LO Gengar is pretty nuts in OU. This is an offensive team that is designed to work around big threats like Mega Medicham, Tapu Lele and Zygarde while still having strong offensive threats. Check it out :]
Sup Joey, I've got this dope OU team that abuses Tapu Lele's psychic terrain with Volcarona and Hawlucha, I think you would really enjoy playing it. I recently hit 1700 points on the OU ladder with it. Hawlucha is a serious threat in this meta that everyone is sleeping on! Keep up the awesome...
