I've got a Magnezone that is my first truely EV trained pokemon, with 252 in HP and 252 in Spc Attack. Although this does move points out of other stats, he could take down 60s at lvl 34. He (or it) has some great attacks and is shaping to become one of the most powerful I've ever made.
I'd just like to ask if putting all points into HP and Spc atk wasn't a mistake is all.
