Introducing Ultra-Mental Plus by Mark Strivings with thanks to the genius of Joe BergFinally! An 'Invisible Deck' effect that actually looks like a regular deck of cards!
Anything that you can do with the classic 'Invisible Deck' can be done with Ultra-Mental Plus, and just as easily.
So, if you already do the Invisible Deck, and would like for it to look like a regular shuffled deck, now you can!
PLUS! I have included a killer effect in this manuscript.
I call it "Ultra Ultra Mental"
I'll describe it for you here, but be sure to keep the underlined points firmly in mind as you read this...
A deck of cards is introduced, removed from its box, and left face up on the table. The deck is in full view (NOT in the box) and on the table the entire time. A regulation die is also introduced.
"We're going to play a game of choice and chance," says the performer, who then asks his helper to name any card in the deck. This is a 100% free choice, and can even include the card that is face up on the deck as it sits on the table.
"That is your choice. Here's the chance." The performer hands the die to his helper and has them roll it a couple of times to prove that it is a regular die. It is finally rolled one final time. Let's suppose that the helper chose the Eight of Clubs as their card, and that they rolled a three on the die. Both of these can be ANY card and ANY number on the die.
"You chose the eight of clubs, and you rolled a three. This is where chance comes into the picture. You can now decide, do you want to go UP a value of three, to the Jack of Clubs, or do you want to go DOWN a value of three, to the Five of Clubs?"
Suppose they choose to go down to a Five.
"Is there ANY way that you could possibly have known that you would end up on the Five of Clubs? ANY way that I could possibly have known? Would you agree that this is a genuinely random selection?"
Anyone would have to agree that this is, indeed, the case.
With literally zero change to the orientation of the deck - in other words, the card that showed on the face when the deck is on the table, is still on the face when the cards are spread, the deck is NEVER turned in any way - the deck is spread, and one card is reversed in the middle of the deck. It is the Five of Clubs. The deck appears to be an otherwise standard, shuffled deck.
This effect kills and leaves no clues. Plus, it's about as easy as it gets.
Keep in mind, just like the classic Invisible Deck, 'Ultra-Mental Plus' has -
ZERO sleight of hand
ZERO complicated calculations. In fact, this is even easier than the original Ultra-Mental Deck in many ways.
ANYTHING that you can do with the classic Invisible Deck, you can do with Ultra-Mental Plus, and just as easily.
PLUS these decks use a special configuration for the roughing, which makes both functions - spreading the deck in pairs AND separating the proper pair when the time comes - incredibly easy and sure-fire.
These decks are prepared by using a roughing stick for this procedure, which means that if your deck ever starts to wear out, you can easily refresh it by using a roughing stick on it (readily obtainable from your favorite dealer).

Fits perfectly, good value
Size: normal
Fits on my eufy perfectly! Now I have a spare set and can wash one. Not too expensive, so I won’t feel guilty when it’s time to throw them away

Absolutely amazing! Working flawlessly for over a month, so far.
Color: White
I am very pleased with the performance so far. The strengths are the ease of setup, the accuracy of its mapping and carpet/floor recognition, the quality of its cleaning and mopping, and the entertainment of just watching. There are weaknesses. The documentation is sparse and pretty useless and tech support has been ghosting me..no responses. So hunt and peck with the App, mostly. Hard to really customize by trial and error. While it vacuums very well, it does not empty as well, really requiring the owner to manually empty the dust bin. No big deal. Maintenance recommendations are hidden on the website and I suspect it is advisable to do some maintenance after every use. The strengths win, however.

User friendly, Pet Hair Approved, Quite Powerful Robot Vacuum
Color: White
We prviously had an Eureka E10 vacuum and mop robot for 4 years. We had no idea what we were missing until we purchased this Narwal Freo X10 Pro.
It maps very fast.
It is extremely quite.
The vacuum then mop with a refreshed mop head solution is much better than dragging around a robot mop pad with no way to clean it without removing and washing it.
We have 3 Australian Sheppards that shed alot. This was the number one concern, whereas the prvious unit needed daily attention. Not a single hair tangle in the floating rotating brush of this unique Narwal Freo X10 Pro Robot vacuum.
4 months of no robot management is wonderful.
The application was easy to use with a ton of customizable options.
The AI option to recognize various floor types and throw rugs ensures a complete clean and quick simple setup.
Lastly the price vs product was very reasonable.
Great product! After spending many months researching, we are glad we made this investment.

After five months, it's basically a brick
Color: White
We've had this robot for five months, and it isn't durable. It worked fine for a couple months. But now it works fine for maybe 20 minutes and then just starts spinning around or going back in forth in the same area wasting its battery. The endless troubleshooting does not help. Cleaning all the sensors, resetting the robot, remapping the house ... Nothing helps. It is only being used in about 1100 sq ft of total space, so it's just not that complicated. It's been trying (and failing) to vacuum our smallish living room for nearly five hours, after several resets/etc. Back when it did function, the vacuum is rather loud if you want it to actually pick up anything big enough to see. The vacuum and mop are both terrible at inner corners, and the intersection between rugs and hardwood flooring is a total miss. There's like a 12" strip along all rugs where mopping never occurs. Definitely not a machine to be used without supplemental sweeping and mopping. The machine insists on starting rugs at the corner, so it pulls up even pretty heavy rugs sometimes. It's sucks up items like socks instead of avoiding them. Also, the machine has never successfully left alone no-vacuum rugs or no-go areas, so some rooms (like with high pile rugs or Christmas tree stands) just don't work without physical barricades. Really, really makes me miss the old reliable roombas...
