Which Card Packs increase during Cards Blast?
Classic Packs, Magical Packs, Royalty Packs, ExtraRare Packs, and Diamond Packs may include extra cards during Cards Blast.
However, not all of these packs are guaranteed to qualify. Be sure to check for the Cards Blast visual indicator (glow) on each pack.
Beginner Packs and any packs you get for the Daily Reward calendar are not included in the Card Blast event.
