As far as I know there's nothing about this in the OP. In my Abra solo run I genned its least powerful egg move in (Knock Off for Gen 4 I believe). It's what I would do in this situation. I looked Ralts up and it has no damaging egg moves (making it even more annoying), but I'd gen in Will-O-Wisp because you could defeat a Poochyena with it, the only thing you have to do is keep your Ralts alive.
I don't know if this is allowed either, so if you want to get on with your challenge and be sure I'd guess you could PM the OP?
This was the first run I decided to record and I had quite a lot of fun doing it. You do think a lot more about not making any mistakes (and I made quite the few), but I still made it through victorious.
