Every game gets a score based on two criteria:
- Popularity (60%): how many players rated it, the hype around it and its popularity on IGDB.
- Rating (40%): the players' average, weighted by the number of votes. A game rated 95 by 3 people does not beat one rated 90 by 10,000 players. A game without a rating is never penalized.
All games are then ranked by score, and rarity depends on the rank: the top 0.5% are Mythic, the next 2% Legendary, and so on.
- Mythic0,5 %128 games
- Legendary2 %513 games
- Epic5 %1 282 games
- Rare12 %3 079 games
- Uncommon25 %6 420 games
- Commonthe rest14 253 games
A rarity never changes. Once given, it is locked, even if the game gets more popular later. Your Mythic stays Mythic.
Not to be confused with the odds shown on each booster, which are your chances to pull each rarity. And sometimes, a card comes out as a Full Art…
