There is no difference. Move Cards. vs. Add.

When you click “Add” in the Change Deck window, that allows you to create a new deck to which to move the cards, instead of moving the cards to an existing deck. Did you get this window?

But it isn’t intended to create new versions of the cards in that newly created deck – it will still just move the existing cards you have selected. If that’s what is happening, that’s expected.

yes,i got this window,but the result is moving the cards to the new deck,not create a new one.the card will be disappear from the old deck.

sometime,I need to create a new sub deck from a large deck,it is important to keep the large deck not be modified.

Yes, it creates the new deck and moves the cards to it. Cards can only be in one deck/subdeck, so that’s exactly what you should expect. You don’t want multiple copies of the same card in your collection.
