I've recently bought myself a set of "ESP Origins" cards and I really like them.
The marks are subtle but easy to read and the general design and look of the cards is very appealing. You do not to see the full back design to get your read (as with Beyond ESP and P@r@l@bs) but you cannot read from a single corner either (as with MK-MOD and Royal). It is still a single glance read, certainly one of the easier, quicker systems, but not located in the corner of the card.
You get a 5x5 marked set (blue back) an extra marked set of 5 (red back) and a bunch of gaffs.
Users of the Outlaw Effects 'Reflections' book test may be interested to learn you also get a marked set of number cards 1-5.
The booklet that comes with the set is pretty cool. It has 10 illustrated routines, listed below:
Synchosis - Max Maven
Viewed ESP Prediction - Richard Osterlind
My Charlier Shuffle - Armand Porcell
ESPitome Location - Sylvain Mirouf
ESP Vision - Armand Porcell
ESP Taytelbaum - Ludovic Mignon
Protocols - Christian Chelman
Marked Thought - Bob Mason
ESP Mind - Sylvain Mirouf
ESP Assembly - Armand Porcell
Similitude - Armand Porcell
EDIT: The booklet is available in English, if you're ordering from Marchand du Trucs, just specify that's your language choice in the 'Extra Information' box on your order.
You also get a second, slimline card box in the package, that fits a 25-card set.
I like them very much and they have, for now, become my go-to ESP testing cards.
Ted, if you get a chance / have the inclination to add them to the initial list, here are the details:
