You guys shouldn't just pull out random numbers to EV train in. After you've bred a pokemon you EV it appropriately. Like you don't just give 100 EVs in speed because you feel like it, give it enough EVs to ensure that you will outspeed certain pokemon. Give an HP that is divisible by 16 if you're using leftovers. Make sure you have enough Atk/SAtk to OHKO/2HKO something that's important. Like Azelf needs 260 Attack to ensure its Explosion will faint Blissey, so find your IVs and then apply as many EVs to get 260 attack. A lot of you are missing the point here.
