I see that when I build a deck, I have a list of 'Number of Cards in deck' which turns Red if i don't have enough of the card:
However, is there any way to just extract the cards I don't own yet? i.e. I have this deck, and I'd like a shopping list to complete it.
For example, in the above picture, it would just return Agrus Kos, Aurelia, Celestial Ancient, and whatever that cut-off card is.
I see the functionality sort of exists with the "Cost of cards you don't own:" feature, but perhaps this could be expanded?
