I do have a deck which I shared with a friend. After I shared, I added one field of my deck . Now I want to copy this new field into his deck so he also can use it.
We could just use the complete deck but than he will loss his statistics and progress.
Is there a way to compare the 2 decks, if the first field (= Key, unique number) is the same, then copy the new field from Deck1 to Deck2
