So a very cliche strategy I know a lot of players use these days is claiming Surv as evil.
For one this is way too overused which ruins the point of using it since most of the times surv claims are evil.
But in CAA, fake claiming is either
A. Fake claim town and risk getting attacked and having your defense outed (or just dying)
B. Claim survivor and risk getting hung
or C. Claim another Neutral Benign role and try to get away with that.
But claiming NB will likely get you hung as if you're Amne you will be asked to remember someone or if you're GA you will be asked to protect to confirm.
Today I've played some CAA games and fake claimed GA turned surv. (by some games i mean 3)
The first game: I was Juggernaut. I stayed silent (didn't attack anyone) until the endgame, but got hex-bombed.
The second game: I was doctor. Got hung d2 cuz evil town
The third game: I was PB. Won.
tl;dr - Claiming you're Guardian Angel and your target left n1 can easily get you to endgame and possibly win the game
