Survivor: Wales

Survivor: Wales is the first installment of Survivor.

Twists:

 * Hidden Immunity Idol: a pocket-sized talisman is widely believed to be the most groundbreaking twist ever to be created on Survivor. A Hidden Immunity Idol is hidden at each camp, giving a castaway immunity at Tribal Council if played after the votes are cast. The Final 5 is the last time they can be used.
 * Legacy Advantage: a Legacy Advantage is hidden after a tribe swap. It can only be used at the first Merge Tribal Council, or at the Final 6 Tribal council. Once used it gives immunity for that person.
 * Idol Nullifier: The Idol Nullifier is a talisman that can be used at Tribal Council. If the castaway wishes to use it, he must do so while casting his or her vote. At the voting booth, the user must write the name of the intended target on the nullifier and place it in the voting urn, along with his or her vote. If an idol is played on the intended target, the host will verify its authenticity, but will also present the Idol Nullifier, informing the player that the idol has been rendered powerless. If the target does not play an idol, the advantage will be wasted and its user will remain anonymous if he or she chooses to be.
 * Double Tribal Council: at the final 8 Tribal Council after Doug got his torch snuffed, Jeff announced that this tribal council isn't over yet. Remaining castaways had to vote out another person out of their merged tribe.
