Magic Tricks

The idea of this illusion is so clever. I like it but however I had issues with it. The gimmicks. Why didn’t Julio provided a ready made gimmick? I did the thing (without giving away the method) to my card and I did it wrong. And there’s only one card gimmick. So its a matter of life and death. you do it wrong then its dead. He could’ve provided at least 2-3 card gimmick. The starbucks too is useless. Who would use that sbucks business card? Since I did the thing to my gimmicked card incorrectly, then I wasted my money. Still dont understand why he only provided one gimmicked card.
