I love them... they're my favourite card. Did you buy a brick before you tried them out? Kind of risky... but I've never really heard anyone not liking them before. Personally, I like them more than the centurions and the Split Spades.
Not very smart to buy them and then ask what people think about them. This time, though, you have nothing to worry about; they're great cards. You can search my review and check it out if you need more "proof".
