I'm not familiar with wonder trading. I didn't do the Omega Ruby/Alpha Saphire games. Didn't really care for Ruby/Saphire in general.

It's basically a lottery. You put in a pokemon, and get a random one back from someone else. I've traded with people in the US, Japan, Poland, lots of places.

Mainly it'll be what I call 'chain  trading', where you trade what you get until you get something you like/want. Also a lot of fucking ComMons, that you don't need though. My girlfriend got a level 100 mew, and a shiny scizor.
