If you have anyone who can Baton Pass a Substitute, remaining EVs go in defenses to make it that bit tougher (maybe to take a leadkarp tackle ;-) ). If not, put them in speed - there's not much it's gonna help you outspeed, but there's Forretress and enemy Shedinja. And if you get a Choice Scarf Tricked on you you'll outspeed neutral base 84s and + natured base 71s. Not that there's much down there, but hey, anything you can get.
In lower tiers, of course this is all rather more relevant.
