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.
I'm like 99.9% sure that this egg is a flawless male Prankster Riolu with 4 egg moves. If it for whatever reason isn't, let me know. Like I said... there are just too many eggs in my boxes and I didn't double check the one I sent you.
If ur starting breeding my spitbacks (the 4/5 iv pokemon that r no use to me when I breed) I give away for free if any of them would be of use to you. Check the link in my signature (under information on my profile page) welcome to smogon!
