These cards are great for keeping track of your powers especially if you are like me and don't know them off by heart. Much easier than looking them up in the rule book all the time.
The card's themselves are really well made and have a nice feel. Each psychic discipline as a different image on the back of the cards to help distinguish between them. The box has a nice texture and is well constructed so should hold up to being thrown in with the rest of your gear in a bag or box.
