Why would there be a possibility for your warrior to draw Arcane Aura as a gold card draw?!? IMHO this needs to be fixed.
It's on boots, which warriors can equip. Not a bug. I'm going to move this to feedback & suggestions where you can suggest that QD operate differently somehow but this is WAI.
Adding to what Flaxative said; you might find it interesting that if you right-click the cards that are being offered, each card will show which item it is from. In terms of QD gameplay, it makes no difference whatsoever what the item is - but at least it answers the question of "why is this card an option?".
