Effect

Sven Kards is a mentalism tool that allows a magician to force any word, number, or image onto a spectator in a seemingly fair and impossible way. The performer presents a set of blank index cards, which the spectator can freely mix and handle. After the spectator shuffles the cards, they select one—only to find that the magician has predicted or influenced their choice, despite the apparent randomness.

Full Details

Sven Kards consists of loose index cards available in two sizes: 3x5 inches (lined or unlined) and 4x6 inches (unlined). Each set includes 20 pairs (40 cards total) and a bulldog clip to hold them together. The cards are custom-made in the U.S. and designed to look and feel completely normal, with no visible gimmicks.

The key feature is the ability to write or draw anything on the cards, making them customizable for different performances. Spectators can mix the cards face up or down, and the force remains undetectable. The method is based on the Sengali principle, ensuring reliability without complex sleight of hand.

  • Mentalists who want a clean, deceptive forcing method.
  • Close-up and parlor performers looking for a versatile prop.
  • Magicians who prefer self-working or minimal-handling effects.
  • Those who perform for businesses, restaurants, or themed events, as the cards can be customized with logos, names, or specific imagery.
