How about something simpler without an AI? A table top with a deck of cards that one can shuffle, place anywhere on the table, turn over, and rotate. One can use it to play any solitaire card game. It doesn't need an AI. It's like us playing with real cards by ourselves on a table. If you make a Tarot deck it could be used for Tarot readings.
It's just an idea. I like the different type of games in your tutorials and a card game was missing. Keep up the good work. I am going to enjoy part of tonight studying your 2D Turn Based Strategy tutorial.
