Shake Change to Selected Card

Method 1
Have spectator select a card. Use the tilt move to seemingly return it to the middle of the deck. Turn over the top card to show the spectator it is not their card. During this you make a break under the card on top of the deck. Place the card you have shown to the spectator face up on top of the deck. Pick up both cards and perform the shake move.

Method 2
-Perform a triple turnover showing bottom card for the spectator to remember.
-Turn the three cards (as one) back over. Take the top card (which spectator thinks is their card) and place it in the middle of the deck.
-Take the next top card and show the spectator and during this you make a break under the card on top of the deck. Place the card you have shown to the spectator on top of the deck.
-Pick up both cards as one using your thumb and middle finger. Perform the shake move.
