This is such a stunning sequence of visual effects that I'm motivated to learn it despite the
tedious gaffs and limited instruction.
The video was originally recorded in another
language and has now been dubbed over with a repeating music clip (the same one for 17 minutes) and
English subtitles. So for every 10 or 20 seconds of original explanation, you'll get one subtitle
like "cut the deck." Still, the visual demonstration is clear enough that you won't have trouble
understanding the moves.
There's some expectation that you already know some basic card
moves, and this price I think it's fine that they're not explained. There are many YouTube
tutorials if needed.
It will take some effort to make the gaffed cards unless you have some
experience with this sort of arts and crafts, but I think it's worth it for the effect it produces.
In the end, the routine is understandable, clean, and beautiful.
