People create “proxy” decks all the time. It’s one of the dominant ways of testing for big tournaments (when you don’t know what cards you’ll need until you settle on a decklist, but you don’t want to buy every potential card). However, for some reason the casual community doesn’t seem to do this as much. This is somewhat ironic because sanctioned tournaments are the only place you have to use real cards.
