Here are some visual examples:
A stack of cards from Mage Knight. What the heck are those cards below the ice bolt? When I play the game I never refer to the cards by name, since the name is not available to be visually focused on most of the time. Thus the thematic identity of the cards is weaker. Too bad. I love Mage Knight!
A stack of Magic the Gathering cards. You can tell what the lower cards are. I always refer to these by name when playing. Much stronger thematic identity. And usability in a hand of cards.
If a card is never in a player's hand of cards, there is more leeway:
Units in Mage Knight are played to the table, so they look nice and are perfectly usable. And their identity works because you can see the name and picture at the same time.
