After you finish the main Collection, and if time is still left until the event end, Grand Collection starts, as a bonus round.

🃏 In Grand Collection, you complete the same sets by collecting the same cards as in the main part of the event. But set rewards are increased, and the final prize is even more exciting!

🃏 The card stars you have collected from Duplicate cards in this launch of the event, carry over to Grand collection.

🃏 When time runs out, your Badge stays on your profile.
