This is strictly a card manipulation effect, which I really don't care for. There's absolutely no
involvement on the part of the spectator, and I tend not to like those kinds of effects either.
Technically, this is not for a beginner. There are displays which are not common, you have
to hold multiple breaks, lots of handling of doubles, etc. Also, about 1/3 of the whole video is
devoted to a flip flourish, which is totally unnecessary, and not especially easy, given how fumbly
Oz was with it.
The worst part about this effect is that after showing the spectator an
"amazing" transformation, the cards aren't examinable. Like I said, this isn't "card magic", it's
"card manipulation". But if that's your thing, you might enjoy this.
