Yveltal+Mawile Core

[DanielJames]

So I found a core that I wanted to try while browsing different forums: Yveltal and Mega Mawile

Both complement each other well. Mawile checks Yveltal's threats (mainly Xerneas) while Dark Aura boosts both Yveltal's own Dark-type attacks and Mawile's Sucker Punch. I came across this Yveltal moveset:

Yveltal @ Life Orb
Ability: Dark Aura
Level: 50
EVs: 60 HP / 68 Atk / 188 SpA / 4 SpD / 188 Spe
Lonely Nature
- Oblivion Wing
- Foul Play
- Sucker Punch
- Protect

Here's a description about this particular moveset:

"Since I am using LO, with 60 HP EVs I reach 209 HP so recoil is less. With 188 speed I can out speed neutral natured Dialga, Giratina, Giratina-Origin, Ho-Oh, Kyogre, Groudon, Reshiram, Zekrom, Kangaskhan, Moltres, Lucario and Smeargle of course. Rest is dumped into attack. Oblivion wing is really nice as it helps me recover the Life Orb recoil."

I know that there are a few more movesets listed in the VGC 2016 Metagame Megathread on here, but I thought that this one was interesting.

My question would be what would be the optimal moveset and spread for Mawile? Who else would you include on the team?
