Rated by Ron Graham as a top-10 mathematical card trick of the 20th century, Diaconis' mind reader is a magic that involves the interaction with five collaborative volunteers. Inspired by this, we perform a similar card trick in this talk with the upgrade to tolerate bluffing volunteers. The theory behind this trick will be used to develop fundamental limits as well as code constructions for faster delay estimation in positioning systems.
