I'll concede this is a good effect for some people, but it's not for me. It's been noted this
effect requires "strong audience management", but once you toss a deck to someone who's 50 feet away
from you, there's not a whole lot you can do if they decide to be a trouble-maker. I'm not
interested in exposing myself to that kind of risk.
I also think the description is a bit
misleading, where it says, "You name each person's card"... well, sort of. You can NOT say, "Joe,
you peeked at the 6 of clubs, Mary, you peeked at the 9 of diamonds", etc. That's not how the trick
works, but this description might lead you to believe it does. I can understand someone being
disappointed if that was their expectation.
Bottom line, this effect is similar enough to a
Radar Deck, except with that effect, you're far more in control. No need to worry about
troublemakers. Since there are better alternatives to accomplish a similar effect, I can't
recommend this.
