7 Mana 7 / 8 Taunt Battlecry: Replace your hand and deck with Legendary minions.
This seems pretty strong, being a Golden Monkey without having to go through hoops like the Golden Monkey. It's also pretty well stated as a 7/8 Taunt for 7. I can see this being a capstone in something like Zoo as a backup plan if the game goes too long, transforming your deck of chumps into giant Legendaries. Even in control I could see this being pretty nice, maybe in some type of mid-range Warlock? I like the call back to League of Explorers.
