Theatre of the Mind is pretty much exclusively a book of effects. It's very good, and there's a big range of effects.
I've got a few Paul Brook items. One in the Hand, Two in the Bush, Juxtapose, Underhanded, Alchemical Tools, and Chrysalis of a Polymath. I like the first two, but wouldn't perform them, and this is one big example of what I said previously. For One in the Hand and Two in the Bush, you need to carry: 4 marked coins - two of which are of specific denominations, two of which are the same denomination. 2 additional unmarked coins. Also, a handful of change. Also, two of the market coins should be in different pockets. And, for practicality's sake, the other two marked coins should be in a different pocket. Finally, the rest of the change should be in another pocket. That's four pockets, and minimum 12 coins.
