Wow, you even got the correct nature! That's great, I'm glad. When I tried using my guide I wasn't hitting the right frames for the nature so I thought something was wrong, but maybe that was just me haha. Glad it was helpful for you!
If I get a new DS anytime soon I will definitely write an Entralink guide for B2W2. For now, try asking in the 5th gen. RNG help thread.
