I want to know how long it takes you to solve the cards once.

It takes about 10 to 20 minutes to use my own card array. The traditional card array integrates one card in one second for about half a minute. However, this does not mean that I am good at traditional cards, but at the expense of accuracy. It can be used as a magic weapon to help other fortune tellers think, but it usually has little effect, which is more like a hunch than a conceptual integration.
