Well people see Mega Audino on Doubles/Triples and therefore I thought why not use my Offensive Set in a singles match, it'll catch my opponent off guard if they don't see it coming. Also it originally had Surf, but I removed that for Hyper Voice stab since it's a Doubles/Triples Offensive set, and Wish was removed for Protect. It actually would work nice in singles with Wish support.
I realize it's been awhile since you posted it, but do you still have Steven's Shiny Beldum event Pokemon available for trade? I have other event Pokes I can trade for it, Super Sized Pumpkaboo, PGL Tyrunt, an older black/white Shaymin event, JP Diancie event, JP Arceus event (not 100% sure this one is legit but it can be transferred via PokeBank). Let me know if you would like to do a trade!
