Epic Cards | Notion

Epic cards are the least common cards in the game and by default you have a 3% chance to pull a epic card.

They are depicted in-game with a purple-colored frame.
When buying cards, the rarity is chosen first then a card is selected within that rarity. The chance of getting each rarity is: Common Cards: 80%, Rare Cards: 17%, Epic Cards: 3%.
Once all common and rare cards have been bought, the chance to buy Epic Card becomes 100%. And once all cards are acquired, you get the chance to unlock Card Mastery.
