Shame. I had been curious about this one for ages and finally got around to reading the first volume - I had no idea it was based on a card game. Had the story worked, I wouldn't have minded, but there was NO explanation whatsoever (the first page opens with a massive, millenia-old battle between...angels? demons? a group of human with special powers?) & I honestly couldn't tell some of the characters apart, even though there's a character chart included.
