The Discover Magic (Stripper Deck) is a closely guarded secret that aids you in controlling playing cards. With this specially altered deck, you can control a selected card, four Aces, all the cards of a particular suit, and more. (Available in blue only)
With the Mind Reading Deck (Marked Deck) you will be able to read minds, find thought-of cards, and sort through the colors with superhuman speed and accuracy. Know the identity of playing cards without touching them and perform miracles. (Available in black only). DISCONTINUED
Transformation Deck (Svengali Deck) is a powerful illusion. All the cards are different as they select one. Then, you cause every card to become the one they chose. This is not just a good card stunt—it's impossible. But doing the impossible is what a magician does. The Transformation Deck is a powerful tool, but only if it is used properly. (Available in red only).
Each deck Includes an instruction booklet that will teach you a handful of powerful card tricks. Original artwork by Mark Stutzman and designed by David Blaine. Made by the US Playing Card Co.
Out of all three, I prefer the stripper or "discovering" deck. I've always been a fan of any stripper deck and having them in Split Spades format was just an offer I could not pass up. The "cut" on the cards were very professional, smooth unlike some where they're ragged and rough. For the mind reading deck, like others, I think the marking is very obvious can it'll be hard to fool anyone other than laymen. As for the transformation deck, it has it's uses but you have to be very careful about letting the spectator handle the cards. I feel that this is my least favorite because you cannot hand this out for inispection (unless you have the actual 1st edition Split Spades so you can swap after the trick)
The handling and stock is not as great as the 1st Edition Split Spades. However, I personally think the split spades run was the best deck created to date. These cards just do not handle as well and even after breaking into my discovery and mind reading deck they do not handle as well as my Split Spades.
Overall, I'd give these decks 4/5 because of the handling, and I think it would be better if they made an option to have just a regular, non-gaffed, deck of these cards (in all 3 colours). But that shouldn't be a problem if you already have those 3 colours in first edition.
The Transformation/Svengali deck is exactly what you'd expect from a Svengali, just with a cooler back than basic Bikes. With a little work and the right materials, you can easily "transform" this pack into a more up-to-date Mirage deck; I find it gives a lot of Svengali tricks a bit more zing.
I wasn't as fond of the Mind Reading/Marked deck; I actually felt the marks were a little too obvious, but then again, you're talking to the guy who owns some excellent marked decks, including a few Ultimate Marked decks, so maybe the comparison isn't fair. Using them on an audience that isn't wise to marked decks, they'd work just fine as long as you can resist the old "Pick a card; your card is..." trick; it's the deadliest giveaway that you're using marked cards. Forget using them at card games - they'll pass the casual scrutiny of a magician's spectator, but if your players handle them enough, someone's bound to discover the markings, especially if you win just a little too many hands above par.
The Discover Magic/Stripper deck is one of those decks I carry all the time. It's a great alternative to using either Bikes or the cheapo decks with no finish, lousy stock and a silly-looking card back. The cut isn't too shallow for a beginner to cut his or her teeth with and they handle well.
If you're starting out, sure, get all three and get your feet wet; they're fun. If you're a bit more experienced, they'll still make good additions to your gaffed-deck collection and are a pleasant change of pace from the other designs you're used to seeing.
