The Curse of Foresight is currently in Survivor: Tuvalu and the game is ongoing.
The Curse Of Foresight: At the very beginning, once tribes are randomly divided, they will also be randomly divided into tribes once more, seperately, making two completely different divisions of tribes. The division between tribes will alternate after every tribal council between the two tribe sets. This will continue all the way until the merge.
Example: The tribes have been randomly divived into two tribes, with A, B, C, and D in one tribe, and E, F, G, and H in one tribe. Then the tribes would be randomly divided once more, putting A, C, E, G on one tribe and B, D, F, and H on one tribe. The make-up of the tribes would switch between these two options after every Tribal Council.
