Where to find Devil's Advocate Trick

[KingsOwn]

So I watched Daniel Madison´s ¨Self Deception¨ video (which is basically an ad for Devil's Advocate) and was very impressed by what the trick did and wanted to buy it. Unfortunately, he is all out on his website and said that they wouldn't be coming back. I also checked places like Ellusionist, Ebay and Amazon with no success. Any idea where I can find one?

Advocate? The pocket index? The any card named trick?

It's in this book https://madison.cards/products/the-madison-masterclass-collection?_pos=4&_sid=d66a6fad8&_ss=r

This is what I'm looking for:

Here's the link to the video:

It's a lot like the Advocate but a more premium version. The general idea is this: the magician states that he is holding one playing card and asks the spectator to guess what card it is. They guess a card, 7 of Spades (or any other card), and the card is shown to be the King of Diamonds. If the spectator looks closely at the King's hand, however, he is shown to be holding the exact card the spectator names. The magician then tells the spectator that the King of Diamonds represents himself and shows the spectator that, just like the King, he has been holding the 7 of Spades in his hand the whole time.

Thanks!
