Menetekel Deck (3147)

The Mene Tekel deck is a trick deck of cards that is configured in such a
way that you can accomplish the following:

1) someone can freely select
a card and place it into the middle of the deck and it immediately
comes back to the top;
2) someone can freely select a card and you can
immediately know its value; and
3) someone can freely select a card and
you can immediately access a duplicate of the selected card. The Mene
Tekel is also known as a “Self-Shifting Pack.”
