The Jaacann Effect is an any card at any number magic trick where a spectator cuts the deck to select a card and then names any number (with some limitations on the first and last five numbers). This close-up card trick requires the magician to build the deck themselves, offering a deep understanding of the trick's mechanics. It uses regular cards, is angle-proof, and doesn't require sleight of hand or additional devices, making it a versatile and practical choice for magicians.
In this review, David dives into the Jaacann Effect by Totally Magic, an any card at any number trick that stands out for its affordability at $12.50. Unlike other similar tricks, this one requires you to build the deck yourself, which David sees as a plus since it helps you understand the trick inside out. The trick involves the spectator cutting the deck to select a card and then naming any number (with some limitations on the first and last five numbers). David praises the trick for using regular cards, being angle-proof, and not requiring any sleight of hand or additional devices. However, he notes the need for some memory work and math calculations. The tutorial is thorough, with a 33-minute video, a 16-minute building guide, and a PDF. David compares it favorably to more expensive options, emphasizing its value and the creative freedom it offers.
