It can be challenging to find the deck you have in the library, or in your collection. Not all decks are easily defined by words. I'd like to make a photo of an unknow deck, and match it with the shared library in the hub or my own collection. This can also be of use for the new card deck verification process to see if the deck has already been submitted or not. After all, my way of describing a deck might be different from yours. .... Once this is in place many more potentials open up, like reading text from a picture just taken, to automate some steps in the deck submission process
