OSYN

This is shown mostly as a card effect though it can also be used for mentalism with few adjustments, meaning that this is a versatile weapon in your arsenal.

In addition there's a VERY nice little bonus feature that I won't give away but I will tell you makes this effect feel like a steal at the price! Highly highly recommended!

This switch opens up a whole world of ideas for things you can do! From playing around with it, I really like its application for card to impossible location but its versatility is my favorite thing! When you get this, keep a notebook close by because ideas are sure to follow!

When I first saw this effect it looked amazing, and it looked difficult. So I was blown away with how easy the method is. Great trick!

Had to jump on the 50% off sale, and as always, was not disappointed in either the quality of the effects/cards, or the service. Keep up the good work.

I really like this! It’s a very smart switch and floors even my magician friends. Now that it’s available as just a download, it’s far more affordable too, for what you get. It really is very simple to put together on your own, and you’ll get a lot of mileage out of this. 4/5 because the video isn’t as well made as it could be - Mark is a great thinker, but not the best teacher. He tends to get “distracted” on jokes and tangents, and forgetting to show what he’s doing in better detail. I know he isn’t actually distracted and that’s just probably his personality, but it is what it is. Still, no hate, love his stuff.

I've seen tricks online like this and this is better than the invisible deck by far but will definitely take practice and is my favorite card trick ever. Amazing.

This was badass....It takes a little time to get it down but when you do. It will be awesome the things you can do with it. Product is a solid 10 but the creator can be an ass. Much love Mark but youre an ass. Still a huge fan of your work.

What a fantastic download this. Mr Calabrese is very thorough with his teachings, and with a great bonus gifted by Daniel Madison. This download is very much worth your consideration, in particular one of the effects/methods discussed is pretty incredible. For me, the best version on this very inspiring download. I'll let you decide, and find it for yourselves. Best wishes to all!

This is a diabolical trick with a method I will be incorporating in many of my other effects. Thank you, Mark Calabrese!

The only negatives I can think of are a few out-of-focus camera shots during explanation. Everything else is almost perfect. The switch is based on a simple idea but it works very well. What is more, with OSYN you get another excellent trick - The Advocate (by Daniel Madison) - for free.

Such a handy concept to have in your repertoire. Many applications, many mind bending possibilities. I can't wait to use this!

Love the idea, so simple yet astonishing

Ngl this is one of the best purchases I have ever made. With advocate included this is kriminily underpriced

I was reluctant to purchase it at first due to the high price point, but I can now say I am very glad with what I got: The best way to end an ambitious card routines (in my opinion) without needing to carry anything that won’t fit in your pockets. Highly recommend it.

I’ve been looking for a good and easy card switch for a while now and OSYN is really great! It’s really easy and can be done with very little prior knowledge. The teaching is great and I’d definitely recommend it.

this is a really great switch based on Jay Sankey's paperclipped. I would recommend learning both this and paperclipped and using both.

this is simple and genius. anyone can learn this effect in a very short time, if you re a beginner; this is for you. if you re a pro; this is heaven !!!!

This method seems so simple you wonder why you didn’t think of it yourself!! Super simple to make and perform and a must have for any level of magician. I’d also recommend pairing this with the advocate, but still great on it’s own!

I wanted to buy an expensive switching device , and now I dont need to because I bought osyn, and íts better thought it will be.
A complete project , you really dont need other swithes.

nice switch. Comfortable
Strong
Effect like it.

🙏

Very convincing, love the moves and simplicity.

I surprisingly loved this. It even fools you doing it in the mirror. Its so clean and the instructions are great. Simple move for any Mentalist.

Yes, this effect does require some effort and practice, but isn't all good magic supposed to be that way?? Mark has a delightful charisma that showcases how powerful this effect really can be if people are willing to put it into practice. 10/10 would recommend for anyone who enjoys any card magic

Mark this is amazing bro... great product, great instructions!

THIS IS GENIUS!!!!!! Love the routines that come with this effect and will use it during gigs!!!!

Here is the deal.....I use this, I will continue to use this. Maybe it's possible but I can't even imagine how anyone could make further improvements to this move. To be able to remove the paperclip and drop it on the table then unfold the card, bill or billet and hand it to the spectator the whole thing just seems so incredibly fair. Mark provides 4 great routines with this, 2 of which are "mind blown" effects in my opinion, Imagination Card and Signed Card but it can be used for so many other things the provide routines are just the begining of how I will use this. Impossible predictions, dollar bill serial # divination etcl To me, 40 bucks is a great value for something that is so versitile and perfected. Thank you!

I was a little thrown off when hearing how this is done and wish there was a cleaner way but after a lot of practice you will look amazing doing this and I would highly recommend.

HOWEVER: This effect is extremely difficult to learn master and correct angles so you will need to practice ALOT!

I received OSYN as a Christmas Present and was skeptical before it even arrived. Upon opening it and after watching the video, I was disappointed that at least half of the gimmick did not come premade if not all of it, and at $39.99 it would have been nice. That being said, what you are paying for is a utility method and not a gimmick. You get something that you can adapt to suit your performances and The Advocate is a great addition that definitely helps justify the cost. However, if you had already purchased the Advocate, this price is a little steep and if I did receive OSYN as a gift I don't think I would have purchased it. Overall great product and really useful. All in all 4/5 stars.

Genius. I will admit that I was a little skeptical about purchasing this at first. But after watching the video, I absolutely love it! Mark Calabrese is a genius and I can't wait to start using this switch. If you're considering purchasing this product, DO IT!

I, too, was a bit disappointed at the outset when it describes what we'll be sent in the mail. However, I do like the handling and I think the last use of this shown on the video is a very effective and smooth "you could have said anything" prediction. I like it better than the "name any card and that appears in the spectator's hand" use. Now the latter is clearly strong, but it requires more stuff. I think what is shown at the end of the video is good enough and easy enough for anyone to do.

This product is awesome. I was expecting much more with the gimmick and when I first watched the download I was a bit disappointed. However. When I explored a bit with OSYN'S download link provided, there is an extra secret when you purchase the product, which I'm not gonna mention, that I think everyone is going to LOVE, and makes OSYN well worth its price. Finally, Mark's explanation is clear and on point. These reasons are all it takes for me to give it a 5 star review.
