I couldn't imagine any computer beating a human at any Collectable Card Game in the near term. Likewise I'd imagine that computers would be at a insurmountable disadvantage at Deck Builders like Dominion in the general case (in that I could easily imagine a Computer being trained to play perfectly on a specific Kingdom but no where close to a top human on a randomly selected Kingdom).
AFAIK there are no good bridge computer programs. A crucial difficulty is making sense of the bidding phase, and of signals during the card playing phase.
Rest assured that no computer will ever dominate a human opponent at Candyland.
