This is a really great, fast, dueling cardgame. There are relatively few rules and terms (and so pretty easy to teach), but there are so many things you can do and deciding which way to go is rarely obvious. The addition of being able to take over an opponent's card twice per game adds an interesting and integral twist, and allows for fun cards which all seem ridiculously overpowered (but actually are only in the right context!). The art is goofy fun, and a welcome change from the typical fantasy.
They are nicer than having stickers over. Those stickers can be printed on your own for less but we all know about stickers on play boards.
