Best EV's for a mew?

[Master Exploder]

Hey. I recently got a mew thanks to the Pokémon summer day camp, and it's lv 10 so i'm guessing it hasn't been trained.

I want to use this Mew in my team. I think it would be a good addition because it can learn any move.

Anyway, i was wondering, what would you guys think would be the best 2 stats to ev train? thanks :)

Level 10? Thats an awkward level... hacked, or thats as far as I know, hacked.

Its a boltbeamer most likely

It isn't hacked... what...

I went to a nintendo event for it. It's an aura mew..

If a Mew is level 9 and under, then it's hacked.

As for the EV spread, I don't exactly know what to recommand, as there are quite a few options for Mew. What do you want to use it as? Physical / Special sweeper, Baton Passer, or maybe even supporter? Considering Mew is uber, it has a wide movepool for support and the stats for it to carry a variety of roles.

Erm.. i was just gonna use it as an ordinary battler. I think i'm gonna train attack and speed, would that work?
