Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Sorry if i didn't answer but it was very early for me (3am) and fell asleep xD and i just saw a blue screen in the morning haha i can trade now if you want but if you want uts use my diamond fc
I will need to do our trade in two parts if you have the time. You asked for MattJ's Flygon. It's on my Platinum, but I have no room for your Poke on my Platinum.
I'll send you the Flygon first from my Platinum. Just send me a piece of fodder for it. Then, I'll go back on with my Soul Silver to get the Blissey.
