Solution: As @shuteye said:
You did not own those cards. They were on loan from Blizzard as part of the Core set.
Goodmorning,
Today, upon opening my collection after update to new expansion I’m missing previously owned cards from decks such as (in Italian):
I don’t know if I’m missing even more cards that were not in any deck.
The Core set was changed with rotation. All of those cards listed are no longer available in Standard. You can find the full list of changes here with links to graphics within

If you ever crafted/opened those cards you should still have the collectable versions in your collection for Wild otherwise you will need to craft them
You did not own those cards. They were on loan from Blizzard as part of the Core set.
The Core set is a large group of cards that Blizzard loans to everyone for free. But cards do not stay in the Core set forever; every year, Blizzard removes some cards from the set and adds others, to keep the set fresh and interesting.
Those cards were removed from the Core set, so they no longer appear in your collection.
yes I owned those cards, I ;play wild and some arent there (legendaries I crafted) so tired of this happening. wait to maintenance they will return as usual I hope lol
If you crafted them, they should still be in your collection.
When you built the deck, you must have (unknowingly) used the Core versions of those cards.
You can edit the deck, remove the Core cards, and replace them with the original expansion versions from your collection.
Problem solved!
At the start I was quite angry, but if it is really a loan than… I’m still angry but for another reason.
Thanks for the clarification
