ATFUS

ATFUS, "Anytime Face-Up Switch", was a card sleight coined by Ed Marlo and published in the April 1964 issue of New Tops which switches out some cards from a small packet of face-up cards, leaving them with the remainder of the deck, while only appearing to display them.

In 1956, Alex Elmsley published an effect in the Pentagram, Vol. 10, N° 12, september, page 93 called "Still Taking Three - Routine 2" that contained the concept of this sleight (although not given a name).
