[Can't rebuild decks]

Thanks for advice. I been able to complete deck and continue play the game.

But after few defeats by epic black dragon (I want to buy bundle, but game have to many bugs and not very frienly, maybe later) I have too many cards I my Vault (red numbers below) and can't leave deck building screen again. I want to include screenshots but don't know how.

 

One question before I leave: can I somehow rebuild character decks freely(not after quests)?

[Can't rebuild decks]

After quests I could rebuild decks of my characters. But I don't see any Availible cards. I see and can use only cards from the quest.

And now after another defeat I just don't have enouth cards to close deck building screen.
