Why am I not able to use any of the cards that I unlocked from the battle pass and ranking up?

everytime I open a card pack and get a full art or even just unlocking a full art card it doesn’t actually let me put it in my deck and when I try to find it as a usable card it just doesn’t exist?? I’ve tried altering the filters to just show all the cards and looking for them by name but they just don’t appear, and I know they can be used cause I’ve seen them used in other decks but for whatever reason all the full art and some other cards the game says I unlocked just aren’t there. Specially Hop’s Zacian full art, Lillie’s psychic bug full art, among other full arts and non full arts. I’ve tried anything I could think of to figure out how to find them and put them in my deck since i supposedly have them, but they are nowhere to be found. It kinda makes it feel like nomatter what I do I can’t get any new cards that are actually cool ;^;
