This may be considered a beginners trick, just through how easy it is to perform, but Lightning Lady will definitely go down both professionally, or in the pub, and often fools even magicians through it's simplicity.
It comes complete with full routine.
My personal routine is a simple follow the Queen effect.
You clearly show each card (no hiding of flaps or anything!) and trap the queen in the middle of the two plain cards. After slowly re-arranging the cards the spectator is unable to follow the queen, and the hit climax is that the Queen vanishes completely leaving only two cards in your hand.
You now clearly show your hand empty, and pull out the Queen from your pocket.
There is NO sleight of hand, and can be performed in just a few minutes with considerable ease.
