I have a Jolly 'ol Keldeo UT with its PP Max. I clone it since it's an Event and I want to be able to offer it to anyone who missed out. If you'd like one, I can offer it for keeps.
Since you said you have everything else, Deoxys is one I rarely see. How about that? Of course, if you need Deoxys back, I can clone it (involving a change of systems) and send it back 5-10 minutes later. Of course, since I only trade legit. myself (I sent away a Lv.3 Jirachi claiming to be caught in Johto and later got a Wishmaker one, same with a fake Arceus), I'd hope the Deoxys is legit. as well.
