They say the genius is the one who notices the obvious which seems to elude the masses. That definitely appears to be the case here. When you learn the method you will instantly think to yourself "DUH!!!" (for lack of a more fitting term).

I've now performed this hundreds of times and often close with it receiving a room full of applause. I will incorporate three spectators. Each writes down their choice on a piece of paper so nobody else shares with one another until the time is right and nobody is influenced by another's choice.

1st spec: secretly writes a value A-K
2nd spec: secretly writes a suit
3rd spec: chooses either red or blue

Also, this way the color of the box is less of a factor or memory for that matter as we are not simply saying "here think of a card you gotta see this", but rather building a routine and focusing all attention on THEIR decisions and THEIR predictions. But for those who find it an issue I offer this:

I tried using a "neutral" color (white) box for awhile, until I realized that I was the only one who ever remembered what color the box was. Everyone else's minds were on the trick and experiencing the effect. I take the box out, pour out the cards and spread them showing there are no duplicates, and put the box away. They unfold their papers and together come up with one card and one color as a COLLECTIVE. All the attention and memories fall to the spectators. I've never once had anybody ask me about the box being a white box and if they didn't notice the unique box, then they most definitely would not notice the Blue or Red, so I've stopped being concerned with that long ago.

Ok, getting off topic. The point is this a a great trick with an ingenious method. The only limitation is your imagination and performance.

ODD is reminiscent of the Invisible Deck (ID), and both tricks have a strong impact. However, I prefer ODD for strolling purposes for three reasons. First, ODD uses 52 perfectly ordinary cards. It’s true that there’s something “ODD” about the deck and it can’t be handed out for inspection. However, the individual cards are quite normal so that you can slowly thumb through them and allow the spectator to see all their faces. The ID doesn’t look nearly so normal and, in close-up situations, spectators sometimes notice its peculiarities.

Second, I think the effect of ODD is more magical, or at least more inexplicable, than the effect of the IV. In the IV, the selected card flips over. Spectators find this outcome impressive but not bewildering – they imagine that the magician somehow turned over the card. In ODD, however, a red-backed card appears in a blue deck. This seems much harder to explain than a flipped-over card.

The third reason I prefer ODD is that it is easy to make. Two ODD decks can be assembled from two ordinary bicycle decks (and no other materials) in a matter of about ten minutes.

ODD is fairly easy to do – about 3 on a 1 to 10 scale. Angle problems are minimal. Marcus Eddie is a great teacher, although I suggest that you ignore his lesson on how to construct a special cardboard card case for ODD. If you use a metal or leather card case and keep the deck face-up during the first part of the trick, you don’t have to worry about matching the color of the card case and the deck. Otherwise, I highly recommend this trick.

My thinking with this trick was a routine that I had looked at doing with that old favourite The In%$#&^le deck.

If you have that deck you will know the basic idea involved here, though Marcus"s working is completely different.

That said the trick is basic to perform, you have to watch your handling so specs dont get a glimpse of anything, the only angles to watch that I could think of are if you have
people looking up at your hands from underneath.

I you are looking for a quick trick, quick to learn, and quick to do, great for beginners, get it.

The reason for 3 stars would have given 4 is that you will need a couple of other things to make the trick work, and most people will know what you need, and probably have a couple of of those around the place, if not extra expense.

All in all well done Marcus

This trick blows people away and it is super easy to learn and perform.

I modified the trick slightly so you can do it completely surrounded and it requires no practice whatsoever (ok, maybe a couple of minutes).

The card box is not modified and you don't need a card clip or sleeve.

Nobody has guessed how I do it. Nobody has seen anything like it before. Everyone is amazed.

This takes little practice but plays big! It's like a better version of the invisible deck. I highly recommend to all magicians!

ODD allows you to show that your spectator freely selected the only odd-backed card in the deck. It is well thought-out, the choice really IS free, and the display move completely sailed past me, the two times I watched the promo video. This was the main reason I bought it.

It requires a little bit of construction, which shouldn't be a problem. And the display move is so well thought-out that--if you do it properly--your spectators will be convinced they've seen the entire deck. However, the deck cannot be examined at any time. And I don't know how many buyers will be able to use this deck for another trick. I think this limits its use.

The way it's taught requires the use of a clip. You should be able to figure out how to do it without one. And maybe doing it without the clip you could ditch the ODD and come out with a regular deck, should your spectators be hungry for more card magic.

The concept of the "odd" card and the outcome is a good idea, the method is very simple, but Marcus Eddie has spent some time thinking about the diffrent aspects of the trick and making it look convincig. not worth the price, but still a good trick, i will probably use this a litte bit, but it will not be in my everyday reportiar.

Marcus does a nice job explaining this illusion in full.

I thought I knew what he was doing but nope: he got me. I like this because the card is completely examinable. At the end you could sign the card after the illusion and give it away if you like.

It's clean and fast and good for table hopping because as you move from table to table, people will hear the 'others' and pick a different card. And their card is the 'Odd' card.

it's worth it.

No interest :
The effect isn't as good as the brainwave and it isn'et examinable... So no interest
If i've to use a deck whitch isn't examinable it will be the brainwave!

I wouldn't have compared this to the invisible deck if I were Penguin. I tried to like this but I wasn't impressed. I bought it because I thought it had some unique gimmick or idea. It didn't, all of this has been done before. Not necessarily as a brainwave/invisible deck but certainly in other applications.

The benefits of having an invisible deck is that the "trick" is well hidden and can be completely spread by the magician. This one you can't do that whatsoever. If you want an invisible deck with a different color back that you can completely spread, just go with Dai Vernon's Brain Wave Deck, found in Annemann's book, "Practical Mental Magic".
