Nothing, but wonderful! If you love zexal and XYZ monsters then this pack-box-set, I have gotten some duplicates it's not a shock, But there was alot of good duplicate, I've gotten few good number cards and I even got 2 of Number - 32 - Shark Drake, 3 of Number 25: Force focus and 3 of Number:7 Lucky Straight and all types of Djinn (Bass, String, Symphony and Percussion mostly 3 of each), and some Thunder End Dragon and Raidraptor, I was happy to get stuff for my water and other decks, Hammer shark, Tin-goldfish, Aye-iron, Utopia equip monster cards, a few battlin' boxers, mini-guts(pretty good spell card), there's alot of cool cards good for deck building.
