This is how the 2 card block system will work
This system is basically a way to convert the major system into cards. I summarized the shadow system that Lance created. Follow this link if you need more complete instructions or want to read the original. In that link there is also a way to quickly expand into a complete 2704 image list. This is a 2 card system, which means you encode 2 cards with only 1 image.
I will memorize cards in blocks of two, with each block being just one image.
Each two card pair will be matched with another one, one that has the exact opposite suits(For example 2h+8h will be matched with 2s+8h). Spades will be matched with Hearts, and Clubs will be matched with Diamonds. Black to red. This way, I will only require 1352 images.
There are 16 possible suit combinations, but because of that matching^^ there will only be 8 possibilities:
#
# - S,Z,C #
# - S,Z,C
## - T,D ## - T,D
#
# - K,G #
# - K,G
## - P ## - P
## - L ## - L
## - M ##- M
## - J,SH,CH ##- J,SH,CH
## - N ## - N
Number Cards(Ace through 10):
These will take up 800 out of the 1352 card pairs.
We will basically convert every card pair, for example 9c2d(9 of clubs-2 of diamonds) into a 3 digit number. Notice how each of the suit combinations above can be paired to a number. Two hearts or two spades make the same sound as the number 1. A spade and a diamond will make the same sound as a 3.
The suit combination determines the first digit of the three digit number we are making.
The second and third digits are simply the numerical value of the two cards. Ace is 1, 2 is 2, 3 is 3, 10 is 0.
The example above 9 of clubs and two of diamonds would equal the number 992. The first 9 is the combination of the suits, which is ## - P. The second 9 is the first cards number, and the 2 is the second cards number.
992 is a baboon for me.
Notice that 992 could also equal 9 of diamonds and 2 of clubs. This is because that suit combination also converts to P, or the number 9. We will discuss how to differentiate which one it is later.
When the first card is a Queen or a Jack:
Because there are only 8 suit combination pairs, there are still 200 images that havenāt been used. These are 400-499(R) and 800-899(F,Ph,V). These will be used whenever the first card in a pair is a Queen or a Jack.
If a card pair begins with a queen, the suit combination will be represented by the second digit in the three digit number we are making. The first digit will be a R, second digit will be the suit combination(for example: ## - L) and the third digit is the number of the second card. For example; Qh+10h would be RCS=400= Reeces
Same thing with Jacks, except instead of 400ās, Jacks will use 800ās(F,V,PH). Ie: Jh3d= 863= F,Sh,M= Fishmoth
If both cards are queen or jack, the suit combination is the third digit in the three digit number. For example: JhQs would be represented by 841= FRT=FiRe exTinguisher. QsQh= 441= RRD= Roared
Jack or Queen as only the second card in a pair:
When they are only in the second place, a Queen is still represented by an R(4) while a Jack is represented by a T/D. We will once again make 3 digit numbers, but will be adding a S to the beginning of each word. So each of these combinations will be (S)(Combination of suits)(Number of first card)(Either an R if itās a queen, or a T/D if its a Jack).
We need to add the S to distinguish these cards from our normal numbers. For example, if we didnāt add an S, the combination 2sQh would be represented by the number 124, which is already 2s4h. If we add the S, this makes the image unique. Instead of 124=Toner, it is now 0124= Stunner
Kings
A king as the first card in a pair is represented by an H. It goes before the suit combination. All kings in the first place of a pair will follow this formula: (H,)(Suit combination)(Second cardās number). If the second card is a face card, it also goes before the suit combination, like this: (H,)(Face card, so H or R or T/D)(Suit combination).
Here are some examples:
Kd4h= HNR= Henry
KhAh= HST= Host/ Heist
KdQc= HRP(H is king, R is Queen, P is suit combination)= Harp
KsJs= HDS= Heads/ Hoods
If a king is in the second place in a pair, it is silent. It becomes simply a 2 digit number, dictated by the suit combination and then the number of the second card.
Examples:
9dKd= CB(C is suit combo, B is 9)= Cub/Cab
2hKh= SN= Snow/ Sun
QhKh= RS(R is first because face cards precede the suit combo)= Rose
JsKd= DJ= DJ/ Dojo
When there are two kings in a pair, it creates a short word that begins with H and ends with the suit combination. For example:
Ks/Ks = Hose
Ks/Kc = Hat
Tip: The number cards A-10 always go after the suit combination, whereas the face cards(J,Q,K) always go before it.
Again, see this link if you need more clarification.
PS: Lance recommends this: āIt would be advisable to fill out your 3 digit numbers for 0xx, /, /, what ever you want to say with words that do not immediately have a consonant following the ās,ā but a vowel instead. So for 011, āsedateā would be preferable to āstate.ā Itās not necessary to do this all of the time, but doing so will make things easier later.ā This will help when you are later making your 4 digit images that start with 0, because you can easily find words that start with st, sn, sm etc. Follow the link for more info.
Tell me if I missed anything or if anything is unclear. Or you can also ask on the other thread.
Edit:
How to actually use the 1352 images instead of 2704.
I already see that I missed something. I forgot to mention how itās possible to use only 1352 images in this 2 card system. Basically, each card pair beginning with a black card is linked to a card pair beginning with a red card. 2s7h is linked to 2h7s. KcAs is linked to KdAh. Spades are linked with Hearts, Clubs are linked with Diamonds. The image for 2s7h is the same image as 2h7s.
I will link blackfirst cards in a single locus until I reach a card pair that begins with a red card. When that happens, I move on to the next locus, and link red first card pairs until I reach a black first card pair, then I move on to the next locus. I do this until there are no more cards left. There is a degree of uncertainty in how many loci will be used, anywhere between 1 and 26, but it balances out, almost always between 9 and 16 loci.
I just have to remember what the last card pair began with, and I can reconstruct the whole deck. Or, I can always start with either locus 1 or locus 2, depending on whether the first card pair is black or red, and thus differentiate. Even if I forget whether the last card is black or red, I still have 50% chance of getting all of them wrong 
Edit again.
Lance pointed out that I failed to mention the rules about Face/Face card pairs. When a Face/face card pair occurs, the Jacks have to stay as F/V/Ph, they donāt change to T/D. Here is his exact comment:
