Ahhhh Wonder Trade, how I love thee.... I've been grinding my Honedge (now Doublade) and catching every Houndour I see to put up on Wonder Trade, the idea being that hopefully they'll find their way to people with Y (obviously I have X). If you get a Wonder Traded Houndour called Fido, it probably originated from me. I've put up two baby Fennekin (both male, named Dumbledore). Anyhoo, what I've been getting in return has been interesting. From the Japanese it's nearly always a Scatterbug, occasionally a Lv 4 male Pikachu. The only decent trade I've had with a Japanese trader was a Lv 28 FEMALE Eevee who is now happily married to a male WT-ed Eevee called Nick and producing eggs every 5 minutes. I'll put the babies up on WT as they hatch (apart from the ones I'm keeping for myself, of course).
On the other hand I've had some pretty good trades with Americans and Europeans. Nick was from a German trader IIRC. I've also had Hippopotas, Chatot, Simipour, Cubone, Omanyte, Wooper, Ralts, Luvdisc... some of which I've had problems catching myself, others I haven't met yet. The most memorable is a Lv 1 male Froakie, which I was dead chuffed with. Anything I don't want (common Pokemon with Japanese names, for example, I throw back into the WT pot. So sorry guys if anyone's got a rubbish Pokemon from me...
I name all my trades, but I've noticed that very very few of the Pokemon I've received have names, apart from the Japanese ones which I can't read anyway. So, Wonder Traders, do you prefer to get a named Pokemon, or not?
