You know when browsing through public decks there are Game Changers marks so you know what card is a GC in the deck, i think the author of the deck should be able to asign or highlight maybe a different kind of mark to specific cards he or she thinks are important, maybe your win con, the card your should look for when toutoring, or just the card or cards the author thinks are need to make the fun stuff to happen while using his or hers deck, just that, an option for the owner to highlight or show a mark near the card so everyone knows what the idea of the deck is more easily
