This trick is really good. Super simple and can be done with any skill level. But why limit it to just playing cards?. Once you have the the cards necessary to do this you will know what I mean. this can be adapted to anything really. So if you run out of gimmicks. You can actually just use blank business cards once you know the method and handling. If you know anything about card splitting, you could make your own card gaffs. I'm not sure why these ideas weren't thought of or shared in the download, but it's a good alternative if you can't afford to constantly buy refills. By all means you should buy this effect and support the magic. With all this said, it would be really nice if blank business cards could possibly be provided as a future option. Just have them made up the same way as the playing cards are. It would feel more organic. It would also be a good way for us magicians to get away from using playing cards all the time. Just an idea. But overall this is still a really good effect. I'll definitely have fun with it.
