Amaze them at the end. That's what it's all about, right? We can discuss and debate what makes for a great magic trick, but if you can amaze them at the end, you've done your job as a magician. "Everywhere and No Way" is a great magic trick in which you find the Queen of Spades over and over again. It appears, momentarily, that you have many Queen of Spades.

But this trick is all about amazing them at the end. And at the end of the trick you show that all the cards have turned blank. No Queens, just blank cards.

The best part is that "Everywhere and No Way" is a stand-up card trick, meaning that it's designed for a large-ish group of people, ideally 10-30. The moves required are basic and easy to do, and the plot is fun, impossible along the way, and then shocking at the end. No gimmicks are needed, other than a regular blank Deck of cards.
