Every pack is randomized, and each card has a set probability of being pulled. Here's how the odds work and where to find them.
Where to find the odds
Odds are listed on each pack's product page before you buy, broken out by rarity tier or card group. You'll see the probability for pulling from each tier, rather than the exact odds of any single specific card (since a tier can contain many different cards).
How odds are structured
Packs are typically organized into price tiers — for example, a $10 pack on the pack page will display odds for each price tier of the card that can potentially be pulled.
A few things to know
Odds may slightly change as more packs have been opened
Odds reflect probability, not guarantees.
If a pack's odds aren't listed on its product page, contact support before purchasing.
