I had a look at the trailer... Not convinced, tbh. I have a few problems with it from the video.
1) The very first move looks terrible! It's often said that a spectator knowing a move has taken place is just as bad as a spectator seeing exactly how it's done. Well, I watched the video, and the very first move looks almost like a pretty bad pass in my humble opinion. Not to say that the move is a pass (I don't know what the move is), but the very fact that something has very obviously happened (fairly obvious shaking of the hands that mildly resembles a bad performance of the classic pass) already ruins the sleight for me. I don't know whether it's because of a poor performance, or poor sleight construction, but either way, it's enough to make me pass (no pun intended) on this.
I just watched the second time the move is performed, and it looks even worse than the first! I'm sorry to be so harshly critical, I really feel bad, but I just can't help but think this doesn't look particularly good at all, compared to what's out there! I know Chris frequents these forums on occasion, and if you happen to read this Chris, I sincerely apologise for being so critical, and I want to make it clear that I have the utmost respect for you... I just really dislike the look of it! :S
The deck is not coalesced or even, it's smeared like a bad Ego Change, and the fact that a move has taken place is all too obvious and not at all magical. Compare to Shigeo Futagawa's Elevator Move, which does the exact same thing but reversed, and it's clear the latter is far superior - very little motion, and what little motion is completely justified, no visible hand motion, no deck movement, etc.
Aaand on subsequent demonstrations of the sleight, I will admit they look a lot better than the first two... But still a fair amount of regripping and waving and handling the deck! (Again, compare to Shigeo Futagawa's move, or Chris Kenner's Shifty)
The final drop, I will admit, does look very nice, though. However the process leading up to it just doesn't cut it for me.
2) As for the card dropping through the deck... Well, I'm sure someone could come up with a presentational angle for why the card is going down this time... But I still have to ask, why? It feels like a premise created for magicians by a magician for the sake of it. Maybe this is just me, but I don't really see the difference it would make to an ACR routine, and, technically speaking, there are much better endings.
3) As hinted above, I don't feel it adds anything to what's already out there. It's a turn off the rising card idea, but a card going to the bottom is not an original idea by any means. As a sleight, I feel it has flaws (either the construction of the sleight is flawed, or the performance was, and either way, it's an equally bad flaw), as stated above. And it's a reverse of SF and CK's moves... Both of which look better.
Again, I'm sorry to come off so negative, but I just really don't like the look of this. Move monkeys who want to know every single version and variation of elevator moves might be interested, otherwise, I'd give this a miss.
