Why doesn't the Desolate Meadow card pack show in the card listing?

I have a number of cards from that pack, but the pack isn't on the page with the other card packs. Any idea why?

Yeah been wondering this too. keep getting a bunch of cards that don't show up and then a popup that keeps telling me to equip cards... lol?

I’m having the exact same problem, I received cards from quest rewards, right click them. They show up in card books but don’t show up anywhere else and don’t seem to be equippable. Anyone I ask just says “google it lol”

EDIT:
Alright man I figured it out. Some cards aren’t equippable, when you right click them, they go to your “books tab”. The books tab is for your roster of characters, so when you fill up a card book, it gives you a passive bonus to your roster.
When you find an equippable, card it’ll show up on that first tab and you can slot it in. That’ll just buff the character its equipped to rather than your roster.
Hope that helps, it was driving me crazy too.
