An algorithmic stack allows one to calculate the card value (either the next card or a card at a particular position in the deck) without having to memorize an entire deck. The most famous such stack is Si Stebbins. Each method has its pros and cons. Try them out and see what works best for you.

It contains two stacks, each made with 52 standard playing cards that contain bracelet sequences.
The Ruby Stack
The deck is cut and six cards are dealt out to six people. The people with cards that have a red suit stand up. The performer names all six cards.
The Ruby Stack is a full-deck stack where it's very easy to calculate the suit and value of the first card of six consecutive cards merely by knowing which of the six cards have a suit that is either a Heart or a Diamond. Alternatively, knowing which cards are a Club or a Diamond allows identifying the sixth card. The exact same...

Effect: After shuffling the deck, the magician turns away, while the spectator cuts the deck and deals cards face down into two piles, stopping whenever they choose. The magician then reveals the bottom card of each pile. As a kicker, the spectator selects any numbered card, and the magician tells them which card is at that position in the remaining deck. After demonstrating the procedure, the magician never touches the cards again.
Description: If you have taken the time to memorize a stacked deck but rarely put it to use, that's about to change. This effect is powerful and simple to perform....

A double "Any Card At Any Number" effect, fully automatic, with a secretly ordered stack that will practically do all the work for you.
An incredible and Self-Working pair of Card Magic tricks, based on the properties of a variant, unknown to most but in any case unrecognizable to the public, derived from what is probably one of the most famous mathematical stacks... In addition to learn a practical method for building it easily, starting from a new deck, you will find two effects explained here on the theme of "Any Card At Any Number."
In the first effect, the magician will announce...

An exciting mentalism effect in which the spectators themselves, after naming any card in the deck, imagine in their mind that they can find it as the only one still in its 'right' place in a shuffled deck, giving rise to an amazing "A.C.A.A.N."!
This is an original new "Any Card At Any Number" type effect, which will most likely be different from anything you have ever seen before!
"... Kudos for coming up with this stack that lets you find any card in its place... And congratulations also for the method you used... Everything is explained very well and in an understandable way! Great!!!...

This intro price will go up to $12 from October 13, 2025
This series of Suit Ordering Systems is probably the world's first 'super store' for ordering suits. The main purpose of these various Suit Ordering Systems is to create a random sequence of suits while retaining a secret pattern visible only to the performer. The applicability of these SOS methods is for various stacks like memorized, algorithmic, mnemonic or any other type of stacked decks.
In this SOS Volume 5, a new innovative concept of Position Pair Suits is used to create a random suit sequence instead of the obvious red/black...

A powerful new stacked deck utilizing the brand new suit weighted cycle system.
Designed for real-world workers. The BTM Stack offers built-in balance, hidden structure, and performer-friendly flow that unlocks effects with the merging of a cyclical and memorized order. With BTM, you'll be able to achieve rapid divinations, stunning coincidences, and clean, direct miracles - without the heavy mental strain. Easy to learn, flexible in performance, and deceptive enough to fool the sharpest eyes, BTM is a system you'll return to again and again.

Effect: The spectator uses their intuition to produce multiple matching card pairs from two seemingly mixed decks. The magician barely touches the cards, making the effect seem even more impossible.
Imagine this: Your spectator freely cuts both decks, chooses one, and deals cards face down, stopping when they want (no force). You do the same with the other deck. Initially, the cards don't match – but this is by design! Then, through an astounding twist, the spectator's intuition takes over. They try again, and miraculously, not only do the cards match, but two more pairs match as well. ...

In this PDF, I am publishing one of my most treasured secrets. Like The Exception and The Gift, this effect was originally released as a competition here, where the first person to figure out the method (within a one-month time frame) was to be rewarded prize money. However, no one who entered the competition managed to figure it out.
I call this effect The Gift 2.0 because effect-wise it's very similar to The Gift, even though the method is different.
I won't expose the method of The Gift here but I will speak in 'code' and say this: for those of you who own...

This effect is a professional routine strong enough to close your show. It ingeniously hides one of the most powerful secrets in card magic: the Stacked Deck. The magician never touches the deck, eliminating all possible solutions. The spectator shuffles the deck twice or three times, eliminating the possibility of a stacked deck. When the magician reveals the identity of a card at a position freely selected by the spectator, it eliminates marked cards. During the routine, the spectator unknowingly gives the magician all the information they need!
The "Out of Chaos Comes Order" effect is...

This ebook was previously only available as part of Karma Deck Pro. But it is now being released separately for the first time. You, of course, need to own the Karma Deck ebook before you get this ebook.
There are a total of 13 routines explained here. For some of the routines, the performer need not even know the Karma Deck, it is enough if the deck is stacked in that order.

This series of Suit Ordering Systems is probably the world's first 'super store' for ordering suits. The main purpose of these various Suit Ordering Systems is to create a random sequence of suits while retaining a secret pattern visible only to the performer. The applicability of these SOS methods is for various stacks like memorized, algorithmic, mnemonic, or any other type of stacked decks.
So far, SOS Vol 3 was only a part of Karma Deck Pro. Now this is being released separately.
These ideas will be interesting and useful for card magic enthusiasts only.

I have already published a few behind-the-back location effects, such as Behind the Back Location and The Gift. In this ebook, I am publishing another behind-the-back location effect, except this one is, in my opinion, the strongest one. I think it’s more fooling than the aforementioned two. Hence why I decided to call it The Ultimate Behind the Back Location.
There is a full performance video by my friend attached below, but before you watch it, here are some important conditions to keep in mind:

"Great effect, very clever thinking. I really like the double aspect to the effect. Well done!" - Marc Paul
Duplicity - a double holy grail ACAAN - is an exceptional variation of ACAAN that introduces a structured sequence where every action is first performed by the magician and then mirrored by the spectator. This sequencing creates a clear and logical flow, reinforcing the illusion of a true mental connection.
The strength of the effect lies in its methodical and structured process, making the final revelation feel inevitable and astonishing. The use of an app is justified...

A hands-off self-working ACAAN.
Imagine performing the cleanest and most impossible Any Card At Any Number effect ever conceived. No sleight of hand, no interference, no magician's touch after the experiment begins.
A spectator freely thinks of a card. Then, through a random process (reading off the hundreds of a stop watch), they generate a number between 1 and 52.
Yet, when they take the deck and count down to their chosen number, their card is right there.
No suspicious moves, no apparent method. Just an experiment that seems beyond anyone's control - yet works flawlessly every...

"This is an exceptional piece of mentalism that combines some great principles. I will definitely be performing this, and you should too." - Terrence Gilchrist
"I'm a fan of the Unnamed Magician's work in general, but this is, in my opinion, easily among his top 5 best effects. It will leave your spectators with their jaws wide open!" - Wayne Lesley
"What a knockout trick! A true reputation maker." - Tony Bianco
A spectator thinks of a card in the fairest possible manner yet, despite all odds, it was predicted by the magician. If you are a fan of both prediction effects and...

A freely named card. A freely chosen number. A shuffled deck that the magician never touches.
Yet, against all logic, the card appears exactly at the chosen position. No gimmicks, no sleight-of-hand - just an astonishing effect that seems beyond explanation.
Leveraging the power of subtle psychology and indirect use of web apps, The Ultimate ACAAN pushes the boundaries of what feels like real magic.
Please note that you will need a phone, or computer, your own or the spectator's, so that the spectator can visit a particular website that displays probabilities of chosen cards.

What if your birthdate determined your Lucky Card, and what if that card was found in the exact position predicted in a shuffled deck - without the magician ever touching the cards?
With Lucky Card, you introduce a powerful connection between a deck of playing cards and the calendar, leading to an astonishing and impossible revelation. A spectator freely selects their birthdate, discovering a unique card linked to it. Then, against all odds, that very card is found at a specific position in a deck that has been set aside from the start.
Completely hands-off and deeply personal, Lucky...

Every magician is certain to encounter a stacked deck at some point, whether in the early stages of learning or as they expand their repertoire. Understanding stacks not only equips magicians with powerful tools for creating seemingly impossible effects but also sharpens their awareness of how others might use these techniques. Mastery of stacks enhances one's ability to perform complex tricks, analyze routines critically, and develop innovative methods to captivate an audience. Embracing this foundational skill ensures that magicians can perform with both confidence and creativity.
In...

The performer either goes amongst the audience or invites six people on the stage. From a pack of playing cards, six cards are dealt to each of the six people. They are requested to select one card and to place same in their inside pocket. The remaining cards are gathered and thoroughly shuffled and the performer does not handle the cards anymore. At no time does the performer know which cards have been selected. A number of boards with cards on them are now exhibited and shown to spectators. They are to say "yes" when they see their own card, and the performer immediately announces correctly...

MASQ Stack is a rotational or sequential stack that is very easy to learn and looks very random. You should be able to remember the sequence in under ten minutes. Given any card, you will know the next card instantly. Knowing this stack, you can perform almost all the routines out there which can be performed with a Si Stebbins or 8 Kings or similar stacks.
But behind the "MASQ" there is another hidden secret. Once you know the MASQ Stack you can also perform a magic square routine anytime, anywhere to anyone without breaking a single drop of sweat. Absolutely no extra effort is required....

This is my go-to effect. Once you have done this effect, the spectator will believe you can read their facial expressions and more.
If you are looking to: build rapport with spectator(s), learn a memorized deck, and perform jazz-type magic this effect is your incentive.
I have gotten more incredible responses from this effect than any other. The method looks extremely fair. The only sleight, if you call this a sleight, is riffling cards off of your index finger. Learning this effect will make your magic better.
Note: You will need to know any memorized deck perfectly.
