I am a reality TV show where contestants compete in various physical and mental challenges while stranded in a remote location, often facing harsh conditions and social dynamics. What am I?

1. My contestants often form alliances and vote each other out.
2. Hidden immunity idols or advantages can drastically change the game.
3. I emphasize social strategy and manipulation as much as physical prowess.
4. My host is known for their distinct style and catchphrases.
