I just watched DD do his routine on the "Dingle's Delights" DVD. It was in a magician's lecture situation, but as Bill noted, he just said something like: "To make it more interesting, let's turn a card around".
Second, JT is correct, if you simply remove the cards one at a time, after the first 5 cards match, the audience gets the point and you're just killing time. It would make a lot more sense to show the first few one at a time, and then dump the remaining cards out and spread, building to the climax, which is that ALL the cards match in total. If it's perceived solely as a monotonous, unchanging one by one reveal, the trick has no climax. (J. Alexander talks about this concept in the Flicking Fingers book.)
I wonder if it would be possible to do something like this: One packet is in A-Q order in a glass. Spectator shuffles the other packet himself. A card is reversed in that packet, and it is placed in another glass. The ordered cards are briefly covered with a handkerchief, and the face card of the ordered packet now matches the shuffled packet. Both face cards are removed, and the Ace in the ordered packet and the new (non-matching) face card of the shuffled packet show. The effect is repeated, and as the new matching cards are removed, the Ace in the ordered packet and new shuffled face card show. Finally, the handkerchief is just flicked in front of the ordered packet, and the Ace instantly changes to match the card at the face of the shuffled packet. However, that's not all: the magician says that the cards decided to really impress you, and then shows that every single remaining card matches, including the reversed card (which is positioned towards the rear of the packet).
It ain't great, but at least in the scenario above, the effect changes and builds a little bit before the final reveal.
