Help on mega Metagross set and EV spread

[Coogin]

once I saw the base stats for mega Metagross I knew he would be viable in VGC. I'm just not sure what Evs and moves would be most beneficial, here is what I had in mind:

Metagross@Matagrossite

Jolly Nature 4HP/252Atk/252Speed

-Meteor mash/ iron head

-Zen headbutt

-Ice punch/FirePunch

-Protect

-Max attack to give better damage output with tough claws boost

-Max Speed EVs and jolly nature to ensure you at least speed tie other M-Meatgross

-Ice punch to deal with M-Salamence or Fire punch to deal with opposing M-Metagross

Give me youre opinions on the set I'm always open for suggestions.
