On Zygarde maybe run Groundium Z if you're running an offensive DD set and Substitute/Rest/Glare over ESpeed and Protect
For Magearna MDB made a post earlier so you can make those edits
POgre is fine as it is, on Sableye you could run wow over toxic but it doesn't matter that much
Lugia doesn't need two attacking moves, take out CM and run toxic/twave and sub
refresh > wow on darkceus
As a team your team kinda loses to marsh (other than msab) since darkceus isn't max def and mixed LO MRay also looks like a big threat too.
