Where are my cards?

I bought all the chapters of galakrond​s awakening with gold and completed them but i dont have these cards 1.air raid 2.twited knowledge and 3.bomb wrangler
Where are those cards in my collection ? I dont remember i ​dusted them bucause i only dust nerfed cards

I have a similar issue. EVERY SINGLE TIME I log into the game, cards are missing from my decks. EVERY TIME! It’s not that the cards are not there though. When I look them up they’re in my collection but I have to remove the ‘missing’ cards and add the exact same copies that are in my collection. Then, when I quit the game and log in again I have to repeat the same process with other cards. What gives???
