Walking with Superman: Day 12

Yas ti sdrawkcab! Everyone knows that the house always wins in Las Vegas, but the house usually isn't quite so...alive! When Superman and Zatanna find themselves facing walking neon cowboys, a killer Sphinx, and increasingly bizarre bets and odds, it quickly becomes clear that Mr. Mxyzptlk is up to his old tricks. It's up to the Man of Steel and the Maid of Magic to find out what the imp's game is this time, before Sin City is turned completely upside-down!
