May I suggest implementing a feature that lets players take a look at the side bar of most recent battle events while at the defeat / victory screen? Sometimes the opponent can catch you by surprise and you can't even review. It would also make it easier to take screenshots of suspicious card behavior that ends the match, perhaps even prematurely.

Might I add to this suggestion by extending the history sidebar to show all game history, both while in game and post game.
