Also, the Toys R' Us event Arceus is really crappy. Lv 100 with the lowest range on stats. Not good for online battling in any way, shape or form.
Heh? All Legit Arceus's were Lv. 100 and they weren't crappy if you SR'ed or RNG'd for IV's and EV'd him. I haven't bothered EV training mine but I've got a few different natures that I'm thinking of ideas with for Jolly, Timid, Modest, & Adamant. Just basic ones.
