I've come up with a card effect that I think is pretty sweet. Inspired by B'wave (because I knew there must be a better way) this is way cleaner looking and has a reveal that is every bit as surprising and also quirky/ funny. It needs a unique gaff and packet of cards. It does use a couple of very basic slights, so it's not as simple as B'wave but not especially difficult either.

So, what do I do? Do I start writing to publishers? How do I get the idea out there without getting ripped off. Obviously I want the benefits of authorship if others think my trick is good.

Thanks,
David

Submit it to one of the magic magazines.

You could also submit it to the wire on theory 11 if you want. You do have to record your own video of the trick plus explanation.

Penguin Magic has a section for people looking to develop and market new effects. It's designed to help creators connect with people who have complementary skills (writing, video, etc).

You could also reach out to companies (Paltergeist, Blue Crown, Ellusionist, Theory11...) to see what they offer.
