i have the his trick decks, is that the same design here? when I bought them did not think they were his trick decks and would love to have then normal version.
Judging from the box design, I'd say these are using the Split Spades Lions back, which is identical to the "Bicycle Split Spades" trick decks.
You should hang on to those trick decks. While not as many people are interested in the Svengali, the stripper and marked decks are starting to crawl up in price - they're out of print and discontinued. The stripper is a great deck, while the marked deck was at the time of its release one of the cheapest marked decks that was also of good quality.
I always carry two "go-to" decks - one of them is always the SS blue stripper deck. The other for now is a pack of blue Bikes with an extra guarantee joker for doing a few tricks. In time I may use the NOC deck (gotta love that extra queen of hearts!) or perhaps the Mechanic or go back to using USPC Guardians.
I'm really chomping at the bit for these new decks! I hope my budget will survive the encounter...
