Super cool. Taking a crack at rules for a game using this.

Sample game idea: CAKE DECORATION game - players have to try to decorate as many cakes as possible. Requires 10 cards.
One card is the 'design recipe' card and never leaves the base station. It shows an amount of ingredients, ex. "1 cup of buttercream, 3 shakes of sprinkles, 4 squirts of whipped cream".
Players start with either 3 blank cards or 3 random low-amount ingredient cards.
On a players turn, they select from three cards: each card is an ingredient, an amount, and a modifier. So cards could be "1 shake of sprinkles (2x)" "2 squirts of whipped cream (+1)" "1/4 cup of buttercream (+1/4)" (could make variations or add other kinds of things that might go on a cake)
The player draws a card, base station detects which card is missing, and the other two ingredient cards increase in amount based on the modifier value displayed on the card. ex. "1 shake of sprinkles with a 2x" will fully complete the recipe if not drawn for two turns (because 1 x2 x2 = 4 shakes, which is enough for the recipe)
With 4 cards in their hand, if the player can pay for the whole recipe, they win the round and get a point. On win, new recipe appears and all cards in the winning players hand and on the base station get rerolled to new low-amount ingredient cards. Score could be displayed on the margins of the recipe card.
If they cannot pay for the recipe, the player places a card back on the base station. And their turn is over. (Should ingredients be re-randomized when replaced on base station? Should that be a player decision whether to reroll it?)
First player to decorate N cakes wins the game.

I think something like this could make for a viable game with a low number of cards, but could be more fun with a greater number (17 ideally?) which would allow for 3 active recipe targets (+2), using the 4th slot for another ingredient and displaying recipe as a disconnected piece(s) (+1), and larger hand sizes (5 -> +4) to allow for more complex recipes
An interesting game design question is how random you want the cards to be? Fair random would probably be viable, but since the 'deck' can know and make decisions based on the state of cards not connected to the base station, you could deal unfairly if less randomness would make the game more interesting or fun.
