Concerns:
Do I need trick and Aroma on Calyrex?
Should I stick with Calm Mind ogre? Should I run sleep talk or something else?
What do I use for Quags?

That's pretty much it. Thanks for suggestions.

Comments

So in the end, I replaced ferro with ditto, kept calm mind block ogre, and got energy ball and drainig kiss for calyshadow. I got to top 5 , so I am pretty  confident with this team.

Answer 1

For Calyrex, I say pick one or the other, and use a coverage move.

For Kyogre, I say stick with calm mind and remove block and (Yeah) replace it with Sleep Talk.

Also, Necrozma, I think, has too many status moves. 2 is okay, but only one actual attacking move? Just pick 2 status moves and choose a coverage move. Same with Ferrothorn and Yveltal, too many status moves.

Hope I helped! :)
