The Frog Prince
by Michael Close

A cursed card the Jack of Diamonds is folded into an origami frog. Spectator chooses a card from the deck, say the Seven of Clubs. The frog finds the Seven of Clubs in the deck. The climax is the transposition of the two cards. The Seven of Clubs turns into the Jack of Diamonds, and when the origami frog is unfolded it is the Seven of Clubs.

This effect is also taught on Michael Close Signature Effects.
