I was lucky enough to snag one of the review copies of 'Once Removed'. I've read it through a couple of times, but not had time to 'do the work' and perform the effect.
My initial thoughts and a few comparisons to other 'think a card' effects:
This is a very clean and effective way to learn what card a participant is thinking of.
The participant has a completely free choice of card, there is no force or verbal limiting of the selection.
There is some procedure, but it is well justified within the routine and it can all take place in the participant's hands.
It does require some memory work, but the ebook contains all you will need to create your own arrangement that makes sense to you - as with any memorisation, customising the information into a format that suits your own mind makes committing the thing to memory a little easier.
So my first impressions are very good. But this is based on a read-through only, I'm probably a few weeks away from performing it for real.
