I really don't know, but it has a similar look to Ben Harris' color change, SuperFlip.
In principle, it resembles a Duck Change,
In principle, it resembles a Duck Change, using a Visa Switch type handling, just with two cards instead of the deck. Doesn't look nearly as convincing as the Duck Change though imo... But I don't know if this is an actual published change or not.
Also reminds me of a change on Greg Wilson's DVD Card Stunts, but again without the deck.
No. You can't, and don't publish it.So it could be published, with references, without infringing?
