Originally released by Nick Trost in the 1970's, 4 Flush was a great example of how Trost could combine card gimmicks with relatively easy sleights and create surprisingly deceptive packet magic
In this one, he combines a simple card gaff with a popular (and easy) move of Ed Marlo's. The result is quite good.
The original versions of this trick have been extremely hard to find, since about the 1980's, but in the early 2000's, Nick Trost struck a deal with L&L Publishing to re-issue many of his classic packets. And 4 Flush was one of those chosen for the re-issue collection.
The effect (in more detail) is this: magi shows five blank faced cards and one regular 4 of spades. In a sort of magical printing/wild card effect, the blanks all get faces to match the Four of Spades.
The very clever combination of Marlo's sleight with the gimmick, plus another favorite Trost gambit/move to exchange half the cards for the other half (in full view of the spectators' burning eyeballs), make this effect a fooler. You will enjoy practicing and performing this, as it even looks magical to you when you are performing it. :-)
Although the cards are not examinable at the end, the handling is open and clean throughout which does allay much of the spectators' suspicion. Put the cards back in your pocket and move on to another miracle.
