Then I suggest with respect that you do not 'get' OO.
The idea of designing computer systems as a series of communicating 
abstractions of real world human concepts (Classes) came about exactly 
because procedural programming was shown to be unsuitable for large 
scale complex systems.

Starting out with a procedural design then trying to force it into an OO 
model seems to be a lot of work to me. A better approach would be to 
come up with a high level abstraction first, in this case 'CardGame'

Then we start to break the problem down, immediately we can split the 
word into two classes, Card and Game, we have already halved the problem.

Now we take Card, in the real word we know that we don't play a game 
with a single card, we know that a card is a member of a pack of 54, 
another word pops out Pack ... this is a new class. We can now go away 
and develop a Pack of Cards independently of our game ... and it will be 
reusable to boot... THIS is OO

Notice that until now I know nothing about what game I might be 
'designing' in fact I venture to suggest that we will discover, in the 
end that a Game' is nothing more than a set of rules that we can apply 
to our Deck. Our Deck is made up of a number of cards from one or more 
(reusable) Packs. Our Game will use a reusable Dealer who has a shuffle 
and deal methods. Once we have all these Classes in place we can start 
thinking about the rules of the game. The detail comes at the end, not 
at the beginning.

Just my POV
