I don’t know if it’s a bug or that’s how it should work, but it really sucks
i had blue card lvl 2/5 + 12 card colletion. i found another card the 13. but the card Disappeared. didnt get exp.
Well then I realized that every additional card is unnecessary so I decided to delete the 12+ cards and get more Experience.
But when I deleted the cards… the original card also disappeared, and I couldn’t use the set effect/card deck…I had to get it again
