Having some stats and analytics for your cards, how often they are used, how often they are in winning hands, even things as detailed as damage done or kill shots each has in your battlechain would be very useful for people trying to value cards to buy/sell or put into the rental market. The more data available and more unique ways to view user's cards the better.

The way you guys have set up the rental market and deck information for PeakMonsters users is way cool, keep up the great work!
