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.
Haha, I was always away from my 3DS whenever I was posting those, I've been out and about these last few days XP I'm available now if you are :) I've got 4, and I'll need 2 copies plus the original of each please.
Yep, 12 trades. I'll breed you a spitback Farfetch'd after I've completed some of my pending orders. Still want that Prism Scale? I can attach it to one of the garbage pokes I'll be trading you.
I'm pretty sure you can do it as soon as you start a new save file, but the level of the Pokémon you get from it depends on the number of badges you have, varying from Lv. 5 for 0 badges to Lv. 40 for 8 badges.
