I wouldn't go so far as to call it a rip off, but I can't help but think that most people are going to end up massively overpaying for a bunch of decks, and end up with 1 semi-rare deck not worth the cost. Of course they put in the picture a JN, a game of death deck, a red jaqk, etc etc, but I doubt even getting a brick would give you a decent chance at getting a rare deck, especially at only 6 bucks per deck when the DOTM club is closer to 10 bucks per deck.
"fools gold", maybe?
