Well, Espeon's movepool is somewhat shallow, so having a hidden power makes a huge difference for it, especially when your opponent tries to be cute, and switch a steel type into it. HP fire is another good option. And thanks, that means alot :)
as for trade rules, obviously people don't want someone who's on the blacklist/icbb, but you don't have to worry about that. You could post in the dmp thread a bit when you breed something, make yourself known around wifi. You need to list how you clone, and obviously, no hacks... (if that applied to you lol)
if you want, you can have a copy of my modest hp electric dry skin croagunk (31/3/31/30/31/31, Dark Pulse/Vacuum Wave/Bullet Punch egg moves)
