I had a quest that was supposed to unlock 1 Brawl deck for completing 5 unranked Alchemy games. I completed this quest, but the Brawl did not unlock. I see example decks in my deck list, but I am missing the majority of cards for these decks.

I do see 5 example brawl decks, but i'm not able to play any of these because they require wildcards to create cards in order to use any of these decks. The quest reward stated that I should have been awarded 1 random brawl deck.
