Four Stack by Zihu (Gimmick Not Included)

Four Stack" allows you to add an extra punch to the ending of your favorite MacDonald's Aces routine. You'll be able to visually transform 1 Ace into all 4 Aces. What makes it even more deceptive is the fact that it can be handled as one card on the table before the other 3 Aces "disappear" from their stack. So it truly looks like 1 card multiplying into 4.

There is no palming or ditching need. As there is also no glue, sticky stuff, magnets, thread or flaps to be found, you can even hand out the aces for examination at the end of the trick.
