Omni Deck from Palmer's Magic has been a modern classic for card magic.
Imagine that you can now perform the time tested professional effect with a BORROWED COIN!

Oh, and did we tell you the coin is not only borrowed but SIGNED?

Yes, you heard us right. You borrow a coin from the spectator, have the spectator sign
the coin, and then turn the coin into a beautiful piece of Omni Coin with their name still
SIGNED on it.

The best part is that the gimmick is reusable with no refills to buy.

This is a reputation maker with a borrowed and signed object with instant reset, and
guaranteed reactions.

What are you waiting for? This is an Omni effect on steroids.
