It makes sense, as it's really the only Gold card you'll ever need. Being neutral, and zero mana, means you can always fit him in, if there is space in your line-up. (Otherwise you gotta MAKE space for it). This way any victory is going to be treated as a gold victory, and you'll be rewarded with DEC accordingly. Of course I don't think I'd pay that much for it, but good for the vendor. Someone's bound to realize the real value of a Golden Chicken, and pay it. Or else, someone's gonna offer theirs for $37.
