There’s an effect I used to perform when I first started card magic. It’s very simple yet baffling to (most) lay audiences I can't remember where I learnt it from:
Aces, Kings, Queens and Jacks are removed openly.
Four piles are formed: King,Queen,Ace,Jack (x4) while pattering.
The patter I was taught at the time was something like:
In a saloon there were cow-boys, the 4 kings are dealt face up in four piles.
Two brunettes & 2 red-heads came into the saloon to keep them company. Queens are dealt face up on top.
But Indians attack the saloon. Aces are dealt.
And soon afterwards the cavalry comes to the rescue. Deal the Jacks.
Mayhem ensues. Gather the four piles, give the face-down packet a couple of Charlier shuffles followed by a couple of cuts by the audience.
Deal the cards into 4 face-down piles and turn them face up. Each packet contains a 4 of a kind.
So if you have information about this effect, please let me know.
