If you want any kind of performance at all, you'd be better off to 
shuffle a list of pointers to cards.  Of course, that means you have
to build a navigation routine that uses the pointers.

I've tried some schemes for shuffling lines in a field. One way is
to use the random function to select a line in sourceField, then put 
that line after destinationField (and delete it in sourceField).  When
there are no more lines to move, destinationField is a scrambled
version of sourceField.  The speed is not blinding, though.
