Legendary Cards are already some of the toughest cards to pull from a pack, but there are 4 Premium Card types that can replace a Legendary the moment it’s pulled. Premium Cards: ✨ Small Sticker Overlays → 27% chance ✨ Full Overlays → 11.5% chance ✨ Legendary Alt Frames → 7.9% chance ✨ 1-of-1 Serialized → 5.4% chance In Grand Arena, the majority of cards with stickers, alternate borders, or custom art are part of a Series, with a fixed number of unique cards in each one. Collect at least 1 of each to complete it. Example: Collecting all 5 Presale Promo cards completes the Presale Promo Series. Completing a full Series earns 2,000 mXP during monthly snapshots (including duplicates). Holding 5, 10, or all unique Series unlocks additional mXP bonuses per unique Series. There are 18 different Series to collect. So if you ever pull one of these Premium Cards consider yourself extra lucky. Happy hunting!
