Is arceus banned forever in the uber tier? Or will he be allowed eventually...
I think the only reason Arceus is banned right now is there's no way to get one that's not Lv. 100 and thus it can't have more than 100 EVs in any stat and Shoddy can't ban certain EV spreads. When Shoddy 2 comes out (or they make an Arceus event that makes him not Lv. 100), then I assume he'll be allowed in Ubers.
@Jikos: I think Mewtwo always wants a +Speed nature to outrun Darkrai.
