Just a search on Google turns up several demonstrations of it,
maybe e-mailing one of the demonstrators may get an answer.
As can be seen in that clip AS is being used instead of a court card. I think a court card and hearts make more sense.
Those that have my "Vampire Dawn" effect may be able to use one of the vampire cards from that for the effect.
Eugene Burger also had a vampire related effect years back "Dracula and the Sorority Girls" which appeared in his 2nd (?) book but was also later marketed.
I also had another I'd rather forget about in my very first booklet "Mainly Close Up".
Phil Goldstein also had a packet effect in a Linking Ring Parade where pictures of women changed, but don't recall the details, I think maybe one card ended up with tiny holes in it, but don't recall.
