I'm not sure if this has been brought up before, but I would love a way to review your completed multiplayer matches. If possible, it would be great to be able to see your opponents cards and review every move that was made. I know this would probably add up to a tremendous amount of archived data, but perhaps the last match or few matches could be saved for review.
Another online Flash-based game I was in the beta for had a "replay" functionality and it was great to have, even though it merely "recorded" the game from my POV ("hidden" game elements details are still hidden in the "replay") and was still buggy (being in beta)-- but the way it worked was based on the fact that game was INSTALLED on and ran from my PC (so the game data was stored there anyway)... Would appreciate if any dev could reply as to whether this is a possibility at all, since Card Hunter is presently still browser-based (and nothing is stored in a static-state at the user's end)...
