I'm a reality TV show where individuals compete in physical and mental challenges while living in a secluded location, often with strategic alliances and betrayals shaping the outcome. Which show am I?

1. My host is known for their catchphrase: 'The tribe has spoken.'
2. Hidden immunity idols can dramatically change the course of the game.
3. The contestants are often divided into 'tribes' early on.
4. The ultimate goal is to outwit, outplay, and outlast the other contestants.
