Since you brought up Dani Dortiz, he is a "magician's magician." And if you want to learn what he does and how he does it, he is an open book. A true gem of a human being and someone we all look up to in the magic community. He really values sharing knowledge and teaching.

Fair warning, his way of performing and executing his routines is not easy to learn and master. There is no "one single" method that explains an entire routine of his. He stacks methods, as all good magicians do. There are layers and layers misdirection, getting one or two moves ahead of the audience at every stage, using applied psychology with a fair share of sleight of hand in between. That's why what he does seems so freakin' impossible.

But he is very open about teaching it all.

So if you (or anyone) genuinely wants to understand how that routine works, he published it. You can buy it here: https://www.vanishingincmagic.com/card-magic/dani-daortiz-fo...

Again, not beginner stuff. But his books and videos are so great for taking card magic to the next level. He was a student of Juan Tamariz, who is another one of the greatest card magicians of all time ... and who also published so much on magic theory and applied psychology and is an open book when it comes to teaching new magicians.
