It would be nice if you could mark that deck as Built, Building or Wish.

In each status, Invetory and Wishlist would be marked, as follows:

- Built: Cards will be in your inventory, but unavailable for other decks. If you want to build two decks, you have to aquire more cards to acomplish that.
- Building: Cards that you have, in you inventory will be marked as unavailable and remaining wanted cards will be in your wishlist
- Wish: All cards in wish list, and cards tha you have with status Available

In all status, if you have more cards than you need in decks, its marked as available.

Maybe some automation on this state machine would help

Thanks

Such a feature works for those who keep copies for every deck. Some of us just move cards between them. I leave a note card when I take cards out of a deck box that lists the cards and the deck to which they went (e.g., 1 Silverblade Paladin to GoST Commander deck).
