[REQUEST] Is there any way I can salvage my Lax Yveltal?

[Zerorion]

I'm so depressed. I saved without thinking after completing the sequence getting Yveltal in Y. 

My Yveltal is LAX NATURE. ARGHHHHH! 

I was wondering if there were any ways that I could EV train it to make it better, or a build that would ignore how shitty it is    Maybe a physical tank type build?


#717 Yveltal [Lax]

IVs: 30, 31 / 6, 7 / 2, 3 / 31 / 30, 31 / 6, 7



How's this? From the smogon forums. Any other ideas that are less sadly sitting there like a duck?
