Usually, magic effects are most powerful with a presentation, but there are some good exceptions. Arrow is one of those exceptions.
The ink comes alive, and the arrow moves in an impossible manner. Not only is the visual strange and entertaining to watch, but it's also highly adaptable to your 'finding card' routine, making it a working magician's best friend.
We're usually all about street magic, but this one kills in any scenario you can think of, including parlor and formal venues.
This is not your ordinary ink effect. This, is Arrow.
