As the current setting during the match, player needs to click on cards on hands in order to display them in the display area so that he can visualize better the attributes of the card. 

I want to suggest that instead of clicking, the player could just hover the mouse(for computer version) on the cards on hands and the cards would appear automatically on the display area. 

This will save time to player when analyzing all the cards he has on hands, allowing him to make faster decision.
