Basically I've been running this on /r/Vivillon and /r/VivillonExchange.
I've made a Google Form that you can fill out and tick which Vivillons you would like, then add me and I'll give you them.
Its interesting to see the statistics on the most requested, least, etc.
Vivillon Request Form <- Click Me!
These Patterns are nothing special, not competitive, not shiny.
Make sure you ADD me as a friend. 1590-5584-4176
I don't want anything special for them, just what you feel they are worth.
And if that happens to be your native Vivillon, Pokemon that you don't want, or Shinys/Lengendaries then that's fine by me.
