>Dealing with cards that can arbitrarily change the rules of the game would require human-level AI almost by definition, unless you want to manually translate them into code, in which case the system would be unable to deal with new cards. That's not unreasonable at all. No one is expecting you to solve general purpose AI by having the cards interpreted with NLP. And translating the cards' behavior to code is not some insurmountable task. Wizards of the Coast has presumably already done that for the online version of the game.
