Inspired by circuit boards with a sense of science and technology, circuit elements in pink and blue are all over, incarnating as visual currents, flowing and intertwining the entire deck of cards! On the back of the card, the very fine lines of the analog circuit are staggered, spreading out from the central positioning point to the surroundings; Behind the simple lines, the circuit elements of the same theme adds a layer of dark lines to the card face, which looks more distinct; both the court cards and the suit pattern are filled with current lines. Even if you look at it for a long time when practicing cardistry, it will not make people feel dazzled or tired.
