Only for the Fans
This book is clearly for fans of Magic: The Gathering Cards. I don't know anything about this game, but the author is clearly a hardcore fan, and despite a brief mention that it's totally okay if you don't know anything about this game, he quickly begins talking about the game as if you have at least some background. Maybe this would be good for someone who plays this game and needs a reference guide, but not for someone who doesn't know anything about the game.
