Card Sleights - Mexican Turnover

On the table is a face-down Ace and in your hand, a blank-faced card or any other card except an Ace.

The right hand takes its card by the lower right corner, thumb on top and first (i.e. index finger) and second (i.e. middle finger) fingers underneath, the second (i.e. middle finger) finger being bent inward a little of the inner end of the card. The right hand scoops the card by going underneath it from the long side. As the right hand turns over, the thumb moves along the second (i.e. middle finger) finger, transferring the grip to the Ace (which is now held between the thumb and the second finger) and takes that card to the left. The blank-faced card remains on the table.
