Cannot see basic native cards when creating classic deck

Greetings travelers,

i am on website where i can create my deck, copy it to clipboard and input it when i start the game and go to my collections. The problem is that i wanna play classic mode and for example - savannah in hunter i own basic and gold one and the gold one is missing. When i try to input shaman deck - again the same, classic deck, another sh*t happens. when i input it - most of cards are blue - it seems like i have to craft it, but many of them are native basic cards - doomhammer, legendary with windfury, charge, taunt, devine shield and many others. When i click on it - it looks like it can be crafted, but it cannot be - there is no info about dust cost of that card and you cannot do anything. When i simply go to my collections without ipnuting anything and i am trying to create new random deck - there is standard by default and i see every single card - i just own them. How is it possible that when i switch from standard to classic, that i cannot se many basic cards of these heroes?

Sorry for my english. I am trying to explain it as much as i can. For editional questions please react, i will reply.

I tried to restart game, everything. It looks like i have to craft it somewhere, but i own them in standart format.

I KNOW THAT THERE IS A DIFFERENCE BETWEEN STANDARD AND CLASSIC, but thats not the point. I have to understand why my savannah highmane i can input only basic one in my classic deck and i have no option to add golden one that i own.

thank you very much for your answers

its NOT basic cards. Its Core cards, you can’t use Core cards in classic. Only basic and classic. Your gold cards also Core cards, not classic

Basic and Core cards are all free. But Classic cards ALL need to be crafted before playing Classic game mode.

Savannah is currenty a core card , that means all see it and can play it on standard/wild , you see a normal copy and a gold copy but that don’t mean you own it , is a temporary version , and there are no disenchant/upgrade buttons.

Instead if from standard view you filter by Legacy/Classic expansion you can see if you have the real owned versions , here you can disenchant/upgrade.

So in your case you dont own this card in gold.

So if from collection you right click a card and the tag is “Core” is not a real owned copy.
