Metamorphose by Mickael Chatelain (1833-W3)

A spectator picks a card and taking care that no one sees it puts it, face down, on the conjuring table. Whip out a felt-tip pen and begin, on the back of a randomly-chosen card, to make a sketch. The moment of truth has come! The spectator turns up his card, the two of diamonds. Now, show your drawing to the audience, the ace of hearts. Oh dear, your prediction seems to be wrong! Nothing of the kind! A quick tap of the card and your sketch duly turns, in a visually stunning way, from the ace of hearts into the two of diamonds! An awfully quick transformation which will seize your audience by the throats.

Don’t blink or you’ll miss it! An awesome twist!
