The player can obtain hard to find cards at the Altar of Wishes. Nur, who attends the Altar of Wishes, can give out the card, if the player presents enough wildcards. When the Altar of Wishes is first unlocked, only cards from the base set can be bought. One must first obtain 200 cards of the other sets through other means (such as packs or achievements) to unlock that set in the Altar of Wishes. Cards cost a number of Wildcards based on their rarity and the pack they are from. The cost for a card is the base cost for its rarity times the multiplier for its pack, up to a maximum of 21.
