Leftovers or Big Root for Yveltal?

Which one would be more effective for an Yveltal with the following moves to have?

-Foul Play-Oblivion Wing-Sucker Punch-Roost

Currently, I do not have a nature because I am currently shiny hunting for it.Also, should Roost be a move used? If not what would be the best move in this Yveltal set with an item I should use?

Leftovers vs Big Root

Althought Big Root + Oblivion Wing is a decent combo it is not consistent. Yveltal will only be able to gain back HP when it deals damage with Oblivion Wing. Plus, if Oblivion Wing does not do much damages or doesn’t hit, the recovery done will be 0 or close to it.Leftovers, on the other hand, will always consistently heal up Yveltal’s HP.Ultimately, it’s whether you’d prefer a steady and reliable healing, or massive amounts of healing in one go once or twice.

Roost

Roost is a highly recommended move on Yveltal with defensive builds such as yours. If Yveltal has Roost, it’s probably a good idea to have leftovers as you will have a steady stream of HP coming in as well being able to heal up 50% of your total health if you need to do so (eg if you’re on the red HP bar)

If you decide to opt out of Roost, thenToxicorTauntmight work well with your current build

I prefer Leftovers, by my set is different to yours:

I only put in Focus Miss to hit Rock and Ice types ok?
