I tried doing something that seemed to fix the problem last time that happened to me. You want to try again to see if Jirachi will trade this time, or just try some other time?
Are you still on? We can trade now.
I had to breed the Empoleon in Platinum to give it Defog.
Also, since you put the pic of Charizard X in the thread, do you want the Mega Stone as well?
I'm not available tomorrow, or any Tuesdays as a matter of fact.
But I don't have a problem with waiting, so if you can't at all today, I can wait until Wednesday.
