You ask someone to NAME A CARD. No forces. You show that THE DECK IS COMPLETELY BLANK EXCEPT FOR THE NAMED CARD. It’s that simple and it looks that good. The handling is totally self-working and can be learned in minutes, but this is no amateur-magic fad. Professionals are flocking to Holy Blank because it offers a rare, simple, MEMORABLE EFFECT: “I named a card, and it was the only one in the deck.”

There are have been several variations on this theme, from “Blizzard” to “Hummer Deck.” All of them have advantages, but to us, this is strongest blend of practicality (no deck switch required, only one pack used) and strength of effect (all the cards are shown blank and there is absolutely no force; ANY card can be named).

Most importantly, this version has the most fleshed-out presentation, which is included and detailed. Every action MAKES SENSE and appears natural. There are several easy but diabolical psychological convincers that make this already outstanding effect EVEN STRONGER.

The “Holy Blank” package comes with everything you need: the pack of cards and detailed, profusely photographed printed instructions on every facet of the routine.

Caleb Wiles is a devilishly clever magician from Indiana. His genius lies in his ability to make miracles out of relatively simple plots and methods. He is able to squeeze a principle or method for as much impact as possible. Nowhere is this better exemplified than “Holy Blank.”

The notion of showing a named card as the only printed card in a deck is attractive for obvious reasons—it is one of the simplest plots imaginable. The method has always complicated the procedure, and this is only natural. Deck switches, spreading gaffed cards a certain way, a bank of force cards—all sorts of methods have been applied.

What Caleb offers is a presentation that justifies the handling required. In his presentation, nothing feels forced or awkward. Every action makes sense in context. I implore you to pay close attention to the nuances of the script in this effect. Technically, “Holy Blank” is quite easy, but for maximum impact, it must be presented in such a way that your actions are justified by your words.

There are other routines with the same effect, and all of them have interesting features. But none of them give you the balance of practicality and impact that “Holy Blank” offers:
