Every public GitHub repo has a set of collectible trading cards — one for each contributor. Cards are generated from real contribution data like commits, PRs, and streaks, with rarities from Common to Mythic. Open packs, collect cards, and complete the full set for any repo. If you've contributed to a repo, you get your own card. Compete on the leaderboard, earn bonus packs from daily challenges, and share your rarest pulls.
