Eudaemonia is an amazing effect: a really powerful prediction for the spectator.
Effect: The spectator rolls 8 imaginary dice and names a number. The magician takes out the deck of cards and counts the spectator's named number from the face of the deck.
The card to the spectator's number is the chosen card
Incredibly the spectator's card will be the only blue card in a red deck!
Look the video performance.
