The seventh book, features Stairway to Heaven, the amazing book test which allows you to use any Bible as a forcing book. Also, Robert Ramirez's Casting the Spell, an amazing Spelling routine, Four Card Monte (a classically Impuzzle interactive effect) and stand-up tricks the Awful words Trick, Fresh fish Now, and My Word! These are effect using purely cards with words, and carefully disguised mathematical principles. Pure Evil is an amazing hands-off effect in which the spectator freely chooses a number, and finds the card at that number; believe it or not, the spectator is forced a particular evil card in the deck.
