Would like to do a triumph card effect with cards in a box so they can not be touched.
Thinking of randomising the cards 1/2 face up and 1/2 face down. After placing cards in box have audience select suit, color and value of card.
Then remove cards… show all cards now face up except selected card.
Thinking of using a invisible deck but not sure how I can accomplish the triumph effect as incorporated into this
Any Ideas would be appreciated.
Thanks

There are better places to ask this but if you are good enough with a faro that would work.

There is a lot of work of putting an invisible deck into a cocktail shaker, lunch bag cup of noodles etc that would also fit the bill

If you want to perform it with a normal, non gaffed deck, you can look up "Ultra Mental Memorized Deck" by Patrick Redford
