Too much monitization, You cannot do anything with extra card. It's "duel links" so where the "links" to share at? The meta are trash, you have to go through several main and mini or even selection boxes to complete a deck, which is pretty costly. The staples are in old boxes which contains bad cards too, farming gems is already hell and I got rewarded with my already a play set reprinted cards, Thank you for playing duel links.
