Each tier has a base amount of points it rewards. The lower the mint number, the more points get added on top of its base points. So while the Common tier has 10 base points, lower mint numbers can get you up to 50 points. As a result, it's possible to have a Common card with a lower tier number that gives you a higher point score for the leaderboard than an Uncommon card with a higher tier number.
- Common: 10-50
- Uncommon: 20-60
- Superior: 40-80
- Epic: 60-90
- Legendary: 70-100
