Transpo Jacks not only shows a visible transposition of cards, but also clearly shows the transposition of number of cards and that detonates the perceptive mind of the viewer, because it is not necessary to speak the same language knowing that where there were four cards before, now there are two and vice versa. You can do it in an impromptu way, under unlimited conditions, with a borrowed or incomplete deck. In essence, Transpo Jacks provides you with a small but powerful transposition routine with alternatives to do it anytime and without much skill.
