Have you considered Scizorite? Y'know, in VGC15, you only use 4 Pokemon out of 6 and chance are, you may not necessarily use Metagross-mega. You may need another Mega.
btw, you asked the same question twice; I flagged the first one so it can be hidden because you can't ask the same question twice.
Your team looks good otherwise, but why Rash Suicune? Is it an event?

Yeah Rash Suicune was an event, and it was shiny. Thing is, if it was the event I'm thinking of (which happened some years ago), it's not an in-game capture and is not viable in VGC 15. Terrakion also has a weird nature, so I'm assuming both of them were in-game captures and the right natures weren't available for you.

But overall, this is pretty decent team :). I can right now only make vague corrections like switching Hydreigon's U-turn out for Earth Power with Modest nature, Terrakion's Sacred Sword for Close Combat, Mega Scizor with Quick Guard instead of Roost if possible (because in battles that usually last no more than 8 turns, healing is difficult). Well managed team in my opinion :)
