How badges are earned
Twenty-two badges in eight families, earned by collecting. None can be bought.
Zukan has twenty-two badges in eight families: number of cards, collection value, rarity, games collected, vintage cards, sets completed, scans, plus one badge for every set you complete. Each one is earned by collecting; none can be bought, and none sits behind the subscription.
Your profile lists them under Trophies, with the progress toward each locked one: how many you have, how many you need, and what is left.
