Its a trade off - you get to see all four original cards in position at the beginning, you get to see all four change, and then all four reset. Yes, using the deck is a big downside, but consider the appearance of the final phase to a layman - the four cards that they've just seen change instantly and apparantly without using the deck - the finding of the aces in the deck afterwards serving almost as a proving phase - look, they were here all along.
So is it worth using the deck? It makes for some very nice "eye candy" - very "visual" - but I often think that this is mostly for the entertainment of the magician rather than the audience. Magic happens in people's minds - "visual" isn't as important as some magicians seem to think. If your small packet technique is good enough to convince an audience that the two packets are seperate at the beginning of reset, then there is no NEED to be able to show all the cards at various stages in the routine.
Given this argument, adding in the deck is too big a trade off for very little gain, which is why I stick with my favourite reset handling, which is essentially Greg Wilson's "Reset with a Hook". I just put up the Zenneth video because the OP wanted a visual reset and well, it is undeniably that. Its worth noting though that Zenneth is a great card technician, a real world worker and if you take the time to look at some of his other videos you'll find that the reset handling isn't typical of the kind of magic he does.
Cheers,
David.
