I know I'm late to the party on this, but how would you go about getting all of the patterns for this little guy now that the trading scene has died down a bit?

I'm specifically looking to get 2 of each pattern--one male and one female--and I'm not worried about the Pokeball or Fancy patterns at the moment.

I've tried Spewpa for Spewpa and Vivillon for Vivillon trades on the GTS, but that's really slow going and the GTS is full of some bullshit requests for some of the harder to find patterns. There's got to be a better way.

Vivillon thread, I guess.
