May be its just pure bad luck on my behalf, i don't know, but 1 thing i do know is that, i have never been able to collect a gold card hero, direct from the turn of the card's! the only way i have got the gold card hero is through saving my spirits, until i have enough to be able to redeem my spirits for them.
i know that some peeps are very lucky at getting the gold hero cards, while the majority of player's become tormented at the though of spending 22k+ in the Tavern and not even getting a pink hero card! never mind a gold hero card!
As for Free Tavern Tuesday, It don't mean a thing, if you cant get the drop you want!
