Survivor 50 has been anything but predictable, as episode 11 demonstrated that not only is no one safe, but that no one should be counted out until their torch is snuffed. While another twist almost upended the merged tribe's dynamics, the players once again demonstrated that their gameplay is what ultimately matters.
At the start of the episode, the Final Nine players were seen reeling from the latest elimination, and while some relationships were starting to break, others remained unbreakable in the face of what was coming. Case in point, Rick Devens and Emily Flippen, who had been working in tandem for the majority of the game, were seeking and planning new ways to remain together, with the extra advantage of Devens just securing an immunity idol.

Another alliance which was still going strong was the polyamorous game marriage between Cirie Fields, Ozzy Lusth, and Rizo Velovic, as well as Fields’ working relationship with Tiffany Ervin. The duo of Joe Hunter and Jonathan Young had just suffered a loss at the previous Tribal Council, and while both were seemingly still working together, they were keeping their options open to other pathways (much to the chagrin of Hunter, who seemingly didn't get the memo since his first season that Survivor is a game of strategic, social, and sometimes deceitful gameplay). The lone wolf remaining was Aubry Bracco, who was working with anybody and nobody simultaneously.
Therefore, it was only a matter of time before lines were drawn in the sand. Firstly, Survivor's host Jeff Probst announced that the players would be divided into two random groups of four, and each group would need to eliminate one of its members. Young, the only person immune, also had the ultimate deciding power, as he was the only safe person for the night and would get to strategize with both groups and attend both Tribal Councils.

While the twist sounds dynamic on paper, it once again fractured the ever-flowing dynamics of the tribe, as targets, strategies, and plans need to be condensed rather than fluctuate with multiple options. The factor of luck then becomes essential for merely surviving, rather than players relying on the social groundwork each had been building beforehand.
The petit scrambling then began. The group of Devens, Flippen, Fields, and Ervin were divided into two factions: Devens and Flippen wanted to make a big move by eliminating Fields, whereas Fields and Ervin knew the other pair had an idol and wanted to survive the night together.
Fields then started reeling in Young to get the majority of the votes and counter Deven’s idol. Young, who also floated between the "honor and integrity" alliance mindset, while also trying to amplify his resume by making moves. Devens and Flippen also tried to bring Young to their side, but Young appeared noncommittal to both sides.

However, Fields had an ace up her sleeve that no one knew about: she had an extra vote advantage given to her earlier in the game by bestie, Lusth. Fields, however, didn't let her guard down, as this advantage is known in the Survivor world to have a worse record of success than Rizo Velovic at immunity challenges.
Ever since being introduced, the extra vote advantage hadn’t worked for those who had played it, resulting in even that player’s elimination—for instance, Dan Foley at Survivor: World’s Apart. Fields then debated on whether to use her advantage or save it for another occasion, but knew she needed to pay extra attention to anything going amiss at Tribal Council, or would be going home with an advantage in her pocket.
This duality of listening, assessing, and deciding when it comes to having a finger on the pulse of the game is what differentiates good Survivor players from the bad ones, and from those who are exceptional. By Fields keeping her advantage a secret from other players, ultimately sensing she needed to play it regardless of the outcome to have a shot at remaining in the game, while also pulling a tie vote, is truly a masterful class of Survivor gameplay.

The other group, consisting of Lusth, Velovic, Hunter, and Bracco were also deciding between two pathways: either targeting Bracco, making it an easy vote, or making a big move by targeting Lusth. Bracco knew she was at the bottom and was willing to go down swinging, whereas Lusth also sensed he could be in trouble but still debated using his immunity idol, since he had allies (aside from Fields) in his group.
Ironically, both Fields and Lusth gave masterclasses on Survivor gameplay, but Lusth was exactly on what never to do in the game. Firstly, since he gave Bracco all the details about his endgame, thinking she was a juror at that point (remember, he was debating whether to play the idol or not, but still assumed she was going to the jury). That’s a big no-no, especially as you never know what extra twists might come that could change those plans, and never tell that to another person who isn't working with you and who then will use this information against you.
The second, and fatal, error Lusth then made was, of course, not playing his immunity idol, cementing his fate in the game and making himself a juror instead. Similarly to what Andy Rueda did back on Survivor 47, where he also disclosed his gameplay to eventual winner Rachel LaMont and then headed to the jury instead, Lusth’s decision then became an even worse one as he actually had security guaranteed if he had only trusted his gut and had solidified his place instead of gambling it.

Hindsight is always 20/20, both in life and in Survivor, but seeing as Lusth was a five-time player and had experienced a similar situation back in Survivor: Micronesia, it becomes almost unbearable to imagine how things would have changed had Lusth made a different choice. Or if Fields had been present at the same Tribal Council, she would have nudged him in the right direction instead.
A small grace for Lusth is that he did have his allies with him , especially Velovic, and he could’ve flushed his idol had they not betrayed him. However, it is Survivor 50 and no one is truly aligned to anyone but themselves at the end of the day. So, to summarize: it is always preferable to use an idol and flush it, as opposed to leaving with one as a souvenir—twice.
