GTS does have some good moments, I got a female Timid Zorua last night. Some other ones (mostly for Dex filling) were Scolipede, Walrein, and a pretty high level Vanillish.
The requests for lv. 9 and under Zekrom and Reshiram are complete jokes though. Honestly I would love to find a way to get a legit Zekrom/Reshiram in that level range just to mess with the punks showing off their impossible to trade Pokemon.
