I found that the sword dance extreme speed set wrecks shit pretty bad O.O
Even though the TRU Arceus can only have 100 EV's in attack. So when I pokeshift them to black I can properly EV train them with those feather items :O
And no I can't RNG in any way shape or form. I've tried shiny PID RNG where you save on a shiny egg but couldn't get it to work...
