A Card Set is a collection of themed cards. Completing a set gives rewards like assists or boosters.

All sets are available from the start of the seasonal album — you don’t need to unlock them one by one.

When you complete a set (by collecting all 9 cards at least once), you’ll receive a reward, which may include boosters or assists. 

• Early sets usually contain more common cards and offer smaller rewards.

• Later sets include rarer cards and offer more valuable rewards.
