Definitely Ivan the Terrible. Travis and Elisa were flawless in the temple, and they still lost with a very hard layout. There is no temple loss that can't top their performance. Hell, most of the wins have nothing on their loss. Annie Oakley is still a great effort too, but Chandra really should've avoided the Mine Shaft elevator.
Which team do you have sympathy for more - Dead Man's Hand or Belshazzar?
