At the end, I decided to toss this Shiny Arceus. As
flargananddingle said, I won't be satisfied If I'd see an imperfect Pokémon stored near mine and
_Dragon's Pokémon. We got this sort of interest for the flawless 'mons since we've started to RNG in 4th and 3rd generation. This interest has matured when we started to do something for the RNG community (writing guides, makin' scripts and more). So, thanks to
Esmeya for trying her best to reccomend me to keep the Shiny God, but we're probably crazy and there's nothing you guys can do about it. We only want to do these things really well, so I will continue to look for a better one.
Also, I will probably get a JPN PS or a Cyber Gadget to backup my AS save as
keroblade said. ATM, I'm still rateing If I gotta buy one of these.
Thanks!
