I must say the effect is very easy and breathtaking. It's a bit angle sensitive (not a lot) and you
can't hand the card out for immediate inspection like some other tricks, so there's a bit of a
tradeoff, but in my mind it's worth it. As with anything, you'll want to practice the nuances of
this, especially ditching the gimmick, quite a bit before performing. While this is an easy effect,
doing it for a live audience is hard because everybody will want to see the card right away. Get a
good card switch down and you'll be good to go.
