To progress the design a little I'd suggest that maybe, Card is an 
abstract class that exposes (at least) two methods, show() and hide(); 
The default implementations do nothing.

I can't think of a card game that doesn't do at least one of these.

I can also see Pack which contains n Card[s] depending on type (54 hcds 
cards is one pack I can think of)

and also Deck which contains a number of Cards required to play the 
game, at this point the 'rules' are irrelevant.

The contents of Pack and Deck may be the same for some games, in this 
case Deck has a constructor that takes a Pack, semantically however they 
are different.
