"DIAMOND ACES" can be easily performed "Emerald Isle Aces" using gimmick cards."
Have a volunteer split a face down deck of cards. Place the top card of the lower stack on the table with its face down. Repeat this three more times. When the four cards on the table are turned over, they all turn out to be Aces.
