Got my set from Amazon yesterday, and I wanted to chime in about how pleased I am with them. I've not tried them yet with my group, but as we're still learning the system, its just one less thing we need to drag out the tome to look up.
One suggestion though, for a version 2.0, would be a way of figuring out what was on the other side of the card. I realize that for the most part they're stepped up/related conditions, but from a stand point of handing them out to the players, it would cut down on the time needed to find a given condition.
In my case, I've put small labels on the corner of each card with the name of the condition on the other side of the card. Sadly it makes the deck a little lopsided, but it's something I can live with if it means I don't have to keep flipping cards.
If you've ever seen the card-game version of Scrabble called Scrabble Slam, you'll get an idea of what I mean.
