Interesting. Breeding for pent actually isn't that hard. It takes time, sure, but it's not difficult after you do it a few times.
I had the hardest time when I started getting pent Vulpix. But now that I finished with Shroomish, it's easier.
Sorry to seem like a bother, but have you added me yet? You still show up as a provisionally registered friend, and I'm sure I've added your friend code correctly. For reference, the friend code I registered is 2208-5498-1233.
