The really good trick "Coluria" is Trick number 25 in Charles T. Jordan 1919 Thirty Card Mysteries.
This trick has a spectator cut the deck a few times then 6 spectators take consecutive cards from a 32 card deck and the spectators tell what color (red or black ie: hearts diamonds vs clubs spades) their card is and the magician then names their cards.
This is based on the following 32 card wrapping de Bruijn (note that Nicolaas de Bruijn was one year old at that time so the name "de Bruijn" for this wrapping bracelet code did not exist!):
00000010000110001110011110111111

But I really want to talk about how we can easily use another old great "de Bruijn" trick named "Suitability" and how to do it with our mem decks (I think this may be a new discovery? please advise me on this).

This trick has a spectator cut the 52 card deck a few times then 3 spectators take consecutive cards from the cut deck and the spectators tell what suit their card is and the magician then names their cards.

This was a trick in L.W. Card Mysteries published in 1928 by William Larsen and T. Page Wright.
This is also a wrapping de Bruijn type of trick way before its time. It is a 52 card full deck no repeats. It does NOT use the two possible binary digits of "1"s and "0"s instead it uses four possible quadrinary digits (my made up word) in its wrapping bracelet code where each 3 consecutive card suits are unique:
1231423241342132141432333222111444331122441133442234
Instead of 1,2,3,4 substitute S,H,C,D.

I'm sure it took Larsen and Wright a great deal of effort to come up with that sequence! But you will not need that sequence since two days ago I discovered that a full 52 card Aronson (or Osterlind BCS) deck can do this trick as is! with one slight modification: you must have the spectator(s) select 4 cards instead of 3 cards as in the original "Suitability" trick (and you need a different cheat sheet).

Larsen and Wright specify the use of their unique hidden cheat sheet to match the three suit sequence to their specially arranged deck and thus know the 3 cards. They could have 3 or 4 or 5 cards taken since only the first 3 cards' suits are needed to match to the cheat sheet.

If you are an Aronson user then all you need is my sorted Aronson "Suitability" cheat sheet below to quickly find the 4 letter code and thus know the first card (you know the other 3 cards since you have the deck memorized).

If you are an Osterlind BCS user then all you need is my sorted Osterlind BCS "Suitability" cheat sheet below to quickly find the 4 letter code and thus know the first card (you know the other 3 cards since you have the deck memorized). Note that Osterlind BCS using 4 cards has one duplicate pattern: CSHC
-----------------
Oster Cshc=8c dup
Oster Cshc=Ac dup
-----------------
By pure chance these two cards (eight of clubs, ace of clubs) when pronounced with a slight slur sound the same so you should be able to equivoque (fudge) then know the other 3 cards (only necessary if they picked and name CSHC as the pattern. Note 1 chance in 26 performances that this bad thing will happen with the Osterlind BCS deck, zero chance with Aronson).

This trick does NOT work with the Tamariz deck because of too many duplicate patterns (I think because the Tamariz deck is created by doing some perfect faros there are some repeating suit patterns).

The main benefit of this particular system below is that only two consecutive cards need to be picked (instead of four, five or six cards as in other systems) and they can be easily read from 20 ft away and you can use your favorite stack!

Instead of a quad-based debruin based on suits use an octo deBruijn with only two consecutive cards selected from a 52 card deck.

With the below octo-based wrapping deBruijn each card will have three binary bits to express a value of 0 through 7 ie: 111 means seven, 110 means 6, 101 means five ... 000 means zero.

Therefore I propose using a bicycle rider back deck and your favorite stack and apply the below octo-based numbers to mark the back of each card in your stack.

Below is the 2 card octo-based wrapping deBruijn I have created:

0011223344556677
20304050607
1314151617
32124252627
4657

The above is the octo-based debruin to apply to your stack.

Oops, above I see 12 in two places, let's see if I can fix that by making some changes in the last three lines:

0011223344556677
20304050607
1314151617
32764252624
3657

I think the above is perfect IE no duplicate two numbers.

Pros and cons of Aronson/Osterlind BCS vs my Octo marked cards method:

Aronson/Osterlind BCS Pros:
no need to mark any cards
Cons: you must verbally phish to get the suit names, you cannot read the cards.

Octo method Pros:
no phishing is done, the cards can be read from 10 to 20 ft away, you only need two consecutive cards selected (but you could have three or four consecutive cards selected and just hone in on any two consecutive cards to use your cheat sheet), any stack can be used (you are not limited to Aronson and Osterlind BCS)
Cons: The cards are marked but even if in the unlikely event a person notices the dulling, they would have trouble making it meaningful and could likely pass it off as worn cards.

There is an inbetween method that I will call "Hybrid Suitability" (but to my knowledge this can only be done with an Aronson or Osterlind BCS deck). Here is how: Instead of eight binary range, use just four binary range and just code each suit using SHCD or CHSD. I prefer SHCD so that's what I will use here: use my dulling method on each card:

All spades will be binary coded as 001, all hearts will be binary coded as 010, all clubs will be binary coded as 011, all diamonds will be binary coded as 100. Note that diamonds could just be left alone as binary 111. This hybrid technique requires four cards to be consecutively dealt and once you look at the backs of the four cards you know the suit sequence of the four cards and you can look at your old suitability cheat sheet.

The advantage of this hybrid technique is that for any reason you cannot read the markings you have an "out" ie: the ability to verbally phish the suits of the four cards and still be successful with your trick.
The biggest disadvantage of this hybrid method is that you can only do this with Aronson and Osterlind BCS (not with mnemonica or other stacks).

This is so cool. Thank you for sharing. I might use this as part of the lie detector effect (cut, name four suits in a row honestly then lie when you want)

Glowball,

This is some really, really interesting stuff. Thank you for sharing, but please consider posting such stuff in the Secret Sessions part of the forums.

Mike,
I'm not familiar with secret sessions nor the policies around it.

I have seen other fantastic stuff posted here on the Café by some prominent people.

I've always felt that the lazy people will just look on YouTube and that anybody that takes the trouble to read nowadays is pretty serious so I felt that the magic Café is a pretty safe place, but I think I understand your point and will look into it.

Thanks for the tip.

All good! It's just a suggestion. If the posts include secrets and methods, the Secret Sessions is the place for such discussions. Just saying.

Prominent people are still people. You can do better. Smile

Quite interesting, and effect which can be done with some stacks, but not with others. Cool!
