What is Wild card in Albums (Card collections)?

The Wild card is a special card that allows you to get a card you haven't unlocked in the album yet.

Tap Albums → WILD at the bottom of the screen and choose the card you want to unlock.

Wild unlocks a card of the rarity shown on the back or lower.

You can get a Wild:

— for duplicate cards;

— in offers;

— as a reward for purchasing an Event Pass. However, this feature is still in testing and may not be available.

Wild cards have an expiration time. You can check it in the Albums tab.
