Terror Surprise by Steve Hollifield - Trick

You have 2 sets of 12 identical horror cards. Show that each set is in the same order.  The spectator selects a set and you the magician get the remaining set. You mix your cards face down.  Now both sets are no longer in the same order. Now you take the spectators cards and mix them the way they tell you to mix them. When both piles of cards are turned over again they have magically appeared in the same order again. Super easy to do and this comes with 24 top quality specially printed cards.
