What is the mystery surrounding the Ghost Kings? By what force do these mystical cards change? Perhaps simply mere trickery of the eye... or is it? The answers are within but beware the ever-present eyes of the Ghost Kings. This is a great impromptu routine needing only four standard Kings from a normal deck. Before the spectator’s eyes, and with no obvious slights or odd moves, the kings flip face up, face down, etc. Very powerful magic.
