I love this move, and use it at the start of one of my ambitious card routines.
I put their card into the deck, click my fingers then SLOWLY turn over the top card to show it's theirs. Look up, smile, they look amazed, and that's when I do my top change, then go into my ACR at a faster pace.
I've never been caught out yet and mines far from silent.
As somebody else has said as well once you've done the change point at the one card you're holding with the hand holding the deck ( does this make sense?? ) Don't know why but seems to be an extra convincer!
