You are correct, I don't have a Gen V game yet. Just recently started playing past Gen III, haven't even started D/P/Pt yet. Just bought Pt so I'm gonna work my way into BW/BW2 from there. Thanks for the detailed explanation--I do consider myself pretty knowledgeable about breeding and EV training and such, but I was just unsure about the Gen V/Dream World pokemon due to lack of experiential knowledge. It's a shame the DW pokemon can't be traded to Gen IV, I wanted to run a good Sunny Day team with permanent sunlight without having to resort to using a legendary. I guess it'll have to wait for until after I finish Gen IV.

Thanks for the help, I'll be sure to remember your shop if the time comes!
