computer card game design.

Are you talking about a computer card game in which one player plays against one or more computer opponents (not very interesting from a board game design point of view), or are you talking about a game in which multiple players play against each other using a computer or computers to interface their game components and control the game environment (more interesting from a design standpoint).

For the second, there are many things that can be done when a computer is controlling the game. Bids in auctions can truly be blind with no player knowing how much money/monetary item any other play has or bids or has remaining after paying their bid.

Computers can also be used to track truly hidden movement on a playing surface. A player can enter their move and the computer will store that information and give out clues to other players as they search for them.

Regarding card games, Bryk had some great ideas. Generally, anything where information is hidden and kept hidden or where there is a lot of bookkeeping.

My impression of games that either incorporate electronics or are entirely electronic (or played by computer over the internet) is that they are usually inferior to a good game created and played the old fashioned way. I would suggest that you try to find ways to make your game work well without the computer if you can.

Sure, you can't have total control over probability, but there are ways to control such things. Testimony of Jacob Hollow uses numbers on cards to resolve combat. That way, the specific distribution of possible numbers is very controlled.

Gloom has a unique way of changing game states of cards in play as the game progresses.

It's not that I'm against using electronics for an interface when designing a game, I just like to see people come up with innovative and creative solutions to game design challenges that will continue to drive game design forward.
