Hearthstone legend has two kinds of cards: classic card and adventure card. Classic card is the first version of Hearthstone legend, and then adventure card is the curse and adventure mode of Naxxramas. Classic card package is the earliest batch of cards and the largest number of cards. The new card package of goblin vs. dwarf is opened. The new card opened after the version of 125. If you open a card package, you will always open the old classic card package first, because the base is the largest, and most card groups are generally composed of cards from the previous classic card package plus new cards. The new cards are mainly functional cards and mechanical cards. Because the card pool of the new card package is relatively small, the opening of the new card package is often repeated. If only 60 cards are opened at a time, the new card package will still be opened for a long time. The new card package is suitable for the old version that has little demand or is only opened in the arena. This is how the card in hearthstone legend came out.
