I have a crappy Jirachi on my Emerald that I clone and send over to D/P. I usually get whatever I want instantly whenever I put it up for offer. If you want a copy of the crappy Jirachi say so and I'll give it for free. You need to clone it yourself however.
I've found that Raikou/Entei/Suicune also works as nice trade fodder (I use those in FR/LG so they naturally suck).
