What's the difference between ladder card and ordinary card?

A trapezoidal card is called a trapezoidal card because one end is larger than the other. Several people upstairs are talking about simple magic. Liu Qian's magic shuffler will use trapezoidal cards in the Spring Festival Evening, but it is useless to have trapezoidal cards, like a madman shuffling method. You said that all poker tricks use trapezoidal cards, which is wrong. Poker magic mostly uses ordinary poker, and there are several professional techniques, such as breaking and passing, and rarely uses props such as trapezoidal cards.
