No, not the "card" bit, but the ‘mobile’ bit. If you've played any mobile games in the last five years you no doubt feel a pang of pain in the wallet at the sound of it. They all seem to be in a race to bankrupt you as quickly as possible.
To my delight, not only is that not the case with Marvel Snap but - cosmetics and bundles aside - its currency of credits and boosters is obtainable in-game.
