📜 Origin
The phrase comes from the literal pastime of stacking playing cards into a freestanding structure. Cards are light and slippery, so these little “houses" topple at the smallest touch, a breath of air, or a bump to the table. English speakers were using the image figuratively by the 1600s to describe anything that looks impressive but rests on weak foundations. It became especially common in discussions of shaky finances, flimsy arguments, and unstable alliances. The idiom got another boost in modern times as the title of a popular political drama. The exact first figurative use is hard to pin down, but the card-stacking image is the clear root.
