I finally got it to pop through Gigadeon. Thing is, it was only thanks to sheer luck that I was able to pull it off. Basically, after getting smacked away from Gigadeon, I was able to bounce back twords him in such a way that I was high enough to avoid being hit by any subsequent attacks, thus allowing me to finally pull it off.
However, I wouldn't recomend using Gigadeon as a way of getting it, as it seems to rely way to much on luck to actually pull it off.
