Lele-Zam team:
https://pastebin.com/WgjKGXFh
I made this team a week ago and it did well on the ladder, tho getting rocks against stall was an issue and I ended up changing Gravity Rocks Lando for SD Rockium Z Lando-T.
Specs Lele is a menace tho is modest, feel free to put Timid if you think it´s necessary for Zygarde etc
Gastrodon works as a Magearna,Tapu Koko and Greninja answer, tho Ash can be an issue
