When creating a deck for Classic mode, there was a problem that prevents some cards from being placed in the Classic deck. For example: Grommash, Cairne, Doomhammer, Al’Akir, King Crusch, Baron Geddon and many others. All the cards are in the collection, but the game, when creating the deck, thinks that I do not have them
Are you sure you own the Legacy versions of those cards, and not the Core Set copies that are given for free to everyone?
I remember exactly that I created these cards specifically for decks for a very long time, but for some reason I can’t spray them, the game thinks that they are free
Ensure your Filter is set to Legacy or Classic.
Why was it necessary to deal out old cards for only one mode? what is the logic if you have to create them again for another mode
The cards in the Core Set are ‘on loan’. Everyone has them. The Core Set is designed to be changed every so often in order to facilitate balance.
Cards in the Legacy/Classic Set are the Vanilla cards that you had before the Core Set was introduced.
Cards in the Legacy/Classic Set are ‘linked’ If you own a Legacy card, you also own its Classic counterpart. The reverse is also true; if you disenchant a Legacy card, you lose access to its Classic counterpart.
You can use either Core or Legacy cards in a Wild deck, but you can only use Classic cards in a Classic deck, and only Core cards in a Standard deck (along with cards in Sets that are in Standard).
Thanks for the answers, I am already confused in these modes, where there is the same card, but for different modes, a very stupid system
Essentially, the Core Set system removed the need to move unbalanced cards in and out of the Hall of Fame.
Classic was a recent addition allowing players to play cards in decks from the release of Hearthstone, before any expansions were released.
