Try and make it look as if you are pushing an actual deck into the box, because it looks very un-natural the way you have done it there

Nice trick but

Your hands go off camera with the deck and return with the deck and the case. Anyone watching the latest video, though not able to figure it out, would have to be suspicious that both hands and the cards are out of frame for even an instant.

I liked it a lot. I don't know where it originated from though.
