ya was unique decks not whizbang. crazy, money money. what made me wonder what it was about was the golden coin they got for turn two so had to look it up and you get a golden coin if your deck is all golden, then i saw they had only legendaries. time and money indeed.
I'm surprised to find out I actually have 31 golden legendaries. Then again I've spent a good amount of time and money on this game over the years. I've crafted about half of them as they're my favorite ones that I use often, can't remembering opening that many from packs though, but I must've.
Kripp used to collect all golden legendaries and he does 35 legendary deck challenge every expansion. Look up some of his old (before Un'goro) 35 legendary deck videos if you want to see all golden legendary deck in action.
