So I got my hands on a shiny Pupitar and want to EV train it. It is Docile nature, with its only good (not perfect) IV being in Attack. It's not the best, but its a freaking shiny! So I definitely want to use it, but don't know the best way to EV train it. I've seen a lot of setups at 252 ATK/252 SPD/4 HP, is this pretty much the best way to train for a Tyranitar? Any help is greatly appreciated!
