I'm currently breeding for a Shiny Amaura (I don't know how its looks as Shiny so it will be a surprise! for this reason I don't want any clue or description about its Shiny coloration, nor about Aurorus) and I often send 4-6IV modest Amaura with four egg moves at Wonder Trade, generally with the nickname "Y U NO SHINY". After getting early route crap like Zigzagoon or Weedle and worthless bred Pokémon with no more than one perfect IV, I was surprised by a Shiny Barbaracle, freshly caught at Friend Safari, and I didn't even known how it looked as Shiny, so I was even more surprised! It looks kinda weird, and definitely not how I imagined it, and even if it's potentially a clone (or even worse, a Powersave hacked one) I don't care much. Also its nickname is "Cool guy", but lol it's a female.
Then I finished my Wonder Trade session by getting a Brave Bird/Whirlwind/Stealth Rock spitback Skarmory (4IV without attack and SpA). Really nice, given Skarmory is one of my favourite Pokémon, even if I already got one with the same egg moves previously.
Actually this Barbaracle is the second Shiny I ever got at Wonder Trade, the first one being a blatantly hacked Suicune with event moves Sheer Cold and Extreme Speed, but with timid nature and caught on a Love Ball. It happened a while ago, so ever since it is possible that Wonder Trade's hack filters has been improved.
(If anyone has a Shiny Amaura/Aurorus in their avatar or sign, I cannot see it because I'm hiding images on my browser. You have no idea how many gen VI Shinies I was spoiled about before I discovered this possibility.)
Edit: just got another Skarmory with the same egg moves again (plus Drill Peck), but now an Heavy Ball female one! I'm so happy!
