Cerberus by Guy Hollingworth.

Cerberus is an incredibly versatile fake card, with many possible uses. It can be used to simplify existing effects already in your repertoire, supply unexpected endings to routines and provide entirely new handlings.

The routines include: Twisting The Aces, Dr Daley’s Last Trick, Reset, Blank Indicator, Waving The Aces, Rest Blanks. These routines are all typical Hollingworth genius – killer version of the various named plots. Some of the material in ‘Cerberus’ is slightly different to that released later in ‘Quartet’.
