It’s so easy to buy the pass by mistake as the button to buy it hides behind the “I understand” button after you’ve read the rules and once you double click you buy this by accident and blizzard doesn’t give back the gold.
Please put a confirmation on the option to buy this with gold because there is such window asking you if you’re sure in the shop for every item that does even though you are going into the shop expecting to buy stuff but not in the tavern brawl of all places…
