Who on Survivor played a character?

To clarify, which players do you think consciously decided to dumb down/ modify their persona and did so most effectively? Some examples I can think of are most notably Devon, who's deliberately played up his surfer bro persona while having a clearly sharper understanding of the game in his confessionals. Another one is Tony from WaW with his prowess in playing dumb, to the extent that he literally creates a dummy ladder to create a goofball impression of him (he elaborates in his RHAP deepdive).

Who are some other players who successfully employed the "character" approach ?
