Step 1: Deck Setup
Step 2: Pick a Card
Now split the deck and remember which deck has the ace on the bottom. have them put their card on top of the deck WITHOUT the ace.
Step 3: Knowing Where the Card Is
don't go straight to it.
take the deck and pull a random card first. TELL THEM NOT TO TELL YOU IF ITS RIGHT
pull their card , in front if the ace of spades.
pull a final random.
Think for a moment and ask if their card is the middle one.
