Loan deck to friends
A lot of newer players treat their wildcards as a premium. It is hard to know which cards to use them on when look at top meta decks. It would be nice to be able to loan a deck to a friend for a certain amount of time. During that time the original user wouldn't be able to use it. And the receiver of the deck wouldn't be able to edit or use the cards in other decks. I think the receiver should be able to use standard or ranked play, but trying out in the standard play is good enough tbh. I think that this feature would/could result in more revenue for WOtC because if someone tries a new deck and doesn't have all of the wildcards, they are likely to pay for it because they used to have a deck that was fun to play and then they would be missing it. But it is also good to know what you want to craft your wildcards on.
