During Round 2, after 16 idols move on from Round 1, we will be holding a simultaneous “Dark Horse” round that will pit Zelo against one person the Soompi Team chooses to “Staff Save.” In other words, 18 idols will now be participating in Round 2, 16 of which are winners from these current matchups, along with Zelo and one staff save. They will still be competing for the eight spots in Round 4, however, as the rest of the tournament format will not be changing.
