[SOLVED][1.16] How to stop resetting nbt when player dies?

I have a class of items called Ragnarok_Cards. My ideia was creating the item Loot_Box with would spawn a random already seen card.

For that I was registering in nbt of player every time he pickup a card. But when the player dies, the nbt is reset.

How I can stop the nbt from resetting?
( Or if this is not the proper way of storing extra data of the player, what is the right one?)
