Carl Mercurio is, of course, absolutely correct. That IS a fine way to ring a stacked deck in and out - without a doubt. A pretty standard one, in fact, used by many a restaurant magician when switching between sponge balls, coin tricks or whatever. When I wrote my post I was thinking of my own parameters - I only do card tricks, so I use the same deck when I work walkaround. And thus, for me, this won't cut it.
And we are talking about walkaround, for money, right? That was the gist of the post that started this thread, wasn't it? So I would still say that the best stacked deck effects are impractical (assuming you want to work with the same deck).
I will assume that Mark Jensen wasn't having a cheap shot at me when he mentions that "intelligent" magicians know a strong effect from a weak one. But hey, maybe he was. ,
Anyway, the majority of effects in Mike Close's Workers 5, in the sections where he talks about maintaining a stack using out-faros, etc, are very good but not outstanding (I'm thinking here of effects like "King Tut" for example.) That's a pretty good effect but not a "start a new religion" effect, in the way that Steve Ehler's "3 Card Location" is. I mean, that's one heck of a STRONG trick. Similarly, many of the 'built-in' effects in Simon Aronson's stack are just "okay" when you're talking about professional walkaround. A clean version of spelling a card may float a magician's boat in a session, but it's just spelling a card to a layman. Not a great attention getter, frankly. I'd rather do an impromptu effect that will get a huge reaction from a layman - Roy Walton's "Smiling Mule", for example - and save Simon's showstopper stacked deck effects for a formal show.
Admit it, even the best stacked deck effects aren't worth the effort if you have to work a room. I think Steve's trick is one of the best EVER with a mem deck. But here's the thing: the spectator's cut off cards, think of the card at the face of their packets and then SHUFFLE the packets. Bit of a bitch when it comes time to reset, huh? (Oh, except for the last card divined.)
Anyway, the original post asked about walkaround effects. I'm thinking here that maybe he won't have access to a table, if he works the kind of gigs I work - just spekkies hands - so he'd probably appreciate some practical advice. Try 'think-a-card' effects with a glimpse, the Vernon effect, etc. Oh, also a nice R.Paul Wilson effect where the person thinks "stop" as you spread through the cards. That's a strong one, it's easy, doesn't require a table, and has an eerie effect on a female audience member. To my way of thinking, that's commercial card/mentalism for strolling magicians.
