Axel Vergnaud's imagination has struck again. If you mix an omni deck with a holey piece revealing a card, you get Revelia. You receive two blocks, one Batman and one 7 of Diamonds.
Imagine having a spectator choose a card, perform your favorite routine and finish by placing the deck of cards in his hands. When he opens his hand, he discovers that the deck of cards has simply become a block with the value of his card engraved on it. You present a deck of blank cards, with superhero names written on them, the spectator chooses a card, let's imagine Batman, and you place the pack of cards on his hands. You pass the case over the deck of cards and it visually transforms into a block of cards, with Batman's face engraved on them.
