Has anyone thought of using Astor Trio switcher to force 3 cards /show your 3 predictions THEN have your Card duck or Snake Basket find those 3 same cards?

I don't have this, but it seems a good idea to use it as a tool to force cards rather than as a prediction trick where most people would suspect the prop.

IMO this would be a waste of an excellent (and baffling) prop.
There are many ways to force cards.

Well, you do force cards in either case. In one situation you force the cards for a prediction effect and in the other to elevate a Card Duck routine. I find the latter hides the forcing better.

Furthermore, using the prop to force cards for the Card Duck routine does not necessarily preclude from using it for a prediction later on, but a good script will be required. The straight prediction effect where the prop is demo’ed is terrible as everybody will suspect the prop - what else is the audience led to believe?
