(Spirit Crystal isn't on the list.) I use the Glasswing for most battles and it's on the Ultra list with Diamond and Dark Angel. I don't understand this compilation of information but I can tell you I knew Glasswing was an awesome fighter. So, I'm trying to use this info as a reference as to what to feed up.
