Unfortunately I think you're the only one here who would value a SR Amaura, so I don't think you'll find someone willing to do this for you. SRing a legend is one thing, because it has 3 guaranteed IVs. SRing an event just because it is in a Cherish Ball is just frankly kind of dumb. You won't ever get one that would be useful competitively without wasting hours and hours on it (read: thousands of hours), whereas it would take only an hour or two to SV breed a flawless shiny one. If it's something you value that much, then you should probably go for it yourself, but I think asking someone else to put in that much time on a fairly worthless event seems like kind of a bad idea. I may be wrong though, you never know.
Great! I'll retrieve the shinies from Bank for you to clone and I'll be on in a minute.
Do you offer credits in your shop? If so, how about I just trade you the Landorus and Cresselia now, and if you SR something I like I could cash the credits in for it? Also, I'm assuming you want my SR Cresselia, not the RNG'd one, correct?
