In DYAD, you'll find:
AMBIENCE CONTROL: A single card control from the middle of the deck to the top. Originally put out in The Blind Faith Collection (2015). It can also be used as a phase in an Ambitious Card Routine.
SAY STOP: A Selected Card At Any Number where you don't really need to know the number beforehand. Originally put out in Audacious (2013) and as a bonus in C.I.A (2015).
Notes and Credits
Do not confuse AMBIENCE CONTROL with BIZAU CHRISTIAN'S BLIND SQUARE -- they are different.
SAY STOP was inspired by PAUL WILSON'S YAMFACAAN. However, they have different methods.
Running Time: approx. 8 minutes
