I'm getting pretty close to it.. 665 or something. Most of them are title legendaries or those silly ones that come in 3s (The Pixies, the Johto guys etc) I'm working on trying to GTS what I can, but it's pretty slow going. I've basically been sending out some left over Pokemon I was working on from breeding.. Regenerator Slowpoke with 4 IVs for example. People out there will trade for it. Eventually.. I got Regi Steel that way anyway..
Basically working on the Regis right now being they pose the biggest pain in the ass as far as getting my mitts on them. I have a few games I haven't finished yet, like Heart Gold and some of the post game in BW2, but thats like level grindy stuff and I'm being lazy.. even with that in mind, Regis are just such a pain to get to.. so I'd rather give someone a cool poke that's worth something in exchange for one.
Kind of wish I knew where my White game ran off too.. had both Zekrom, Reshiram and Thundurus on there..
