A little bit of advice for EV spreads. There are 3 types of standard spread; Wall/Tank, Fast sweeper, Bulky sweeper. For a Wall/Tank spread what you want to do is have 252 (max) HP and then 252 in 1 of the defencive stats (this is to either help is weakness in a stat (like defence on chancey/blissey) or to further increase a defence (special defence on an umbreon)) and then the final 6 ev's in either the other defence stat or in its attacking stat. For a Fast sweeper you want 252 in speed, 252 in its attacking stat and the final 6 is HP. For a Bulky sweeper you want 252 in HP, 252 in its attacking stat and the last 6 in either of the defences. The reasons for this is though split defences/HP may sound nice in alot of cases they just don't hold up as because you split them you aren't great in either just alright in both and as later game gym leaders have propper EV training very often the split defences just aren't enough to withstand attacks.
