I especially like this effect because there are so many possible ways to perform it. The
instructions are almost unnecessary. You probably need to know a sleight or two in order to perform
the effect for best results, but even someone who knows only the basic sleights can perform Twilight
Angels. The one drawback is that the mirror (ungaffed) provided, is cheap and not especially
reflective. So I would recommend getting a better mirror--anything that's about 1" by 2" will work.
I also recommend using this effect after another card trick as the nature of the illusion differs
from those of other card tricks and makes for a good change of pace. The beautiful thing is that
you can have this set up in a deck you are using for another effect and then proceed to perform it
almost as an afterthought.
