The Be Kind Change is pretty angle sensitive, IMO. It's passable but not something I would perform for large crowds.
A classic pass or sort of a Pugh's pass? I wouldn't use a one-card pass as something deceptive and visual. Though you've got some variations that definitely work like the coffin change/ego change, a classic pass with one card shouldn't be something you want to draw attention to like you would with a color change.
