6. Battle of the Block
Two Heads of Household? That's insanity! No, that's a Big Brother twist!
First introduced in Season 16, the Battle of the Block allowed two Heads of Household to nominate two Houseguests for eviction. Then, each nominee would compete for safety. But wait! There's more. The losing team was forced to compete for the Power of Veto and, in turn, the HoH who nominated said Houseguest would be stripped of his—or her—power.
Got all that?
