What I really miss is a proper Deck Manager.
Storing Decks, Loading .. maybe some quick slots as mentioned in another thread.
The thing with the codes is cool but I'd prefer to have it saved online with my account. I often have months of breaks and by all means, I will lose track of those decks. I also work on many machines.
I don't know how Magic is doing it but maybe there is something that can inspire.
P.S.: You Rock!
