For the Monster Book Collectors...

I plan on getting all 5 of the 5 PQ bosses, ergoth (Because I can't really GPQ) and probably Crimson Rog. I do think it's a bit annoying but then again, I haven't been having such great luck with boss cards (60 hours of Old Fox hunting seems like a lucky break, I know I've spent at least as much at Zeno). Still, I think by buying them you're simply depriving yourself of cards to hunt in the future.
