Those are the evs I would give it ingame. Max Hp gives it overall good defense and better special defense. It has 320 attack stat-plenty enough to do good damage with EQ and RS. It has 325 defense-enough to take quite a few attacks. Counter is a fun option and might kill a pokemon that uses a strong physical attack. Roar is meh ingame, you won't see too many stat uppers ingame and if it has a special move, then you really shouldn't be phazing. It can help with spikes damage. Body Slam is merely for paralysis since donphan's speed sucks. Hidden Power Bug is good if you can get it, helping out with the grass pokemon.
