Perhaps
@RealityOne can help more than I can. I believe he's answered questions for Houdini and Jesus lol
It was actually Moses and the double lift followed by the springing thing with the stone tablets didn't quite turn out that well.
I have no idea where I can find this effect. Or if it exists at all. Any help is deeply appreciated.
As others have said, there are a variety of ways to do this.
The earliest reverse card effect I can find in print in English s in T. Nelson Downs's
Art of Magic, but that one was an old one back there. There also are a significant number of reversed card effects in Encyclopedia of Card Tricks. However, none of those involve springing the cards up into the air, rather merely spreading the deck. Those methods would be able to be used more in dribbling the cards to the floor where there is little risk of the cards changing position
I can think of only one
surefire way to do this based on the springing "up in the air" which would require rifling the deck to select the spectator's card and none of the cards would be examinable.
There are a lot of versions. Shin lim published shinag which is the more flashy version. Michael obrien teaches a version of it free in his youtube channel. Mark calabrese published grab via ellusionist which uses a dribble instead of a spring, but is one of the cleanest versions , ... . There are a lot of versions with different methods, but you can create your own method as well.
None of those have the all of the cards landing on the floor with only the selection face up. However, my favorite effect in that vein is Hit the Deck in
Scarne on Card Tricks.
