Pack Odds

Every pack

Every booster pack holds 6 cards, rolled one slot at a time. These are the exact numbers the game uses. Odds are the same whether a pack is free, bought with gold or bought with gems, and they don't depend on your Leader.

If a set has no card of the rolled rarity left for that slot, the slot gives the next rarity down.

Full Art

Every pack has a 8.3% chance (1 in 12 packs) to swap its lowest card for a Full Art from that pack's set. Full Arts you don't own yet are 2x as likely as ones you have. A promo Full Art also adds that promo card. A repeat Full Art becomes 100 set shards.

Leaders

New players start with 5 Leaders, one per colour. While a pack's colour still has a Leader you haven't found, that pack has a 16.7% chance (1 in 6 packs) to swap its lowest card for one of those Leaders, picked evenly. You never get a Leader you already have, and packs of a colour you've completed never roll one. A Leader's Full Art is a separate, rarer cosmetic pull (above).

Duplicates

You can own up to 3 copies of a card (a full deck's worth). Your 4th copy of a card, and every copy after that, turns into a wildcard of that card's rarity. One wildcard crafts one copy of any card of the same rarity. Every set pack also gives +10 set shards.

Prices

A pack costs 4,400 gold, or 440 gems when you play online. Online you can also trade gems for gold: 100 gems = 1,000 gold, one way only. Gold comes from playing; free packs come from the weekly challenge bonus, the season pass, season events and codes. No single card is ever sold.
