Okay, so I tried the Auto Spring Fan Card Revelation with misdirection to flip the fan over. The idea is that they don’t see me turn the fan over, their attention is elsewhere, and when they look back all of the cards have changed.
Here’s sort of what it looks like (it doesn’t work on camera as it’s an open move that’s covered by misdirection):
The reaction it gets has a delay while people notice it at staggered times, so it’s not at punchy as openly flipping the fan over. Reaction wise, it’s say it’s about the same either way, but flipping it covered by misdirection is a stronger magic trick. What’s nice is that it can be done either way and you can choose at the last minute how you are going to do the revelation, you aren’t really locked into one way or the other.
