This is something I am playing with.
Effect
The basic effect is that four aces are placed into the deck at random locations and then the deck is shuffled multiple times. Then five hands of poker are dealt out, with the dealer getting the four aces.
Method
Start with the four aces on the table. Take a break underneath the top four cards of the deck. Place the aces face up on top of the deck, maintaining the break, now under eight cards. Perform the Braue add on technique, as you display each ace, flipping it face down on top of the deck. On the last ace, you are holding an ace and four hidden cards. Drop them all on top of the deck, with the last ace still face up.
Take that face up ace and perform Marlo’s Tilt move to apparently bury the ace into the deck. Note that below the face up ace are four indifferent cards and three face down aces. Unlike the normal Tilt, where you tilt up one card, this time you are going to tilt up at least four cards, although you can tilt up to seven cards. I usually maintain a break as I flip the aces face down, so getting into the Tilt position is easy.
The spectator thinks the top four cards are aces, in reality, the top card is an ace, and the next three are indifferent. So show the top card and do the Tilt move. Then, one at a time, take the next three cards, without showing them, and with the same actions at the Tilt, actually insert them into different parts of the deck.
Situation check: there is one indifferent card on top of the deck with four aces under it.
Now you are going to perform a standard riffle stack. You can either do a normal riffle stack or use a Zarrow shuffle stack. In the video above I am using a riffle stack.
Cut the top half to the right and shuffle off, holding back the to four cards of each half. Drop the left top four cards, and then the right top four cards.
Cut the top half to the right and riffle shuffle again, shuffling the left hand cards faster, and holding back four cards on the left again. The right hand holds back three cards. Drop the left top four cards, and then the right top three cards.
Cut the top half to the right and riffle shuffle again, shuffling the left hand cards faster, and holding back four cards on the left again. The right hand holds back two cards. Drop the left top four cards, and then the right top two cards.
The stack is almost complete, you need to add three cards to the top of the deck. You could do another riffle shuffle, but what I do instead is to cut the deck, maintaining a break and let three cards riffle off my thumb onto the lower half. I then continue to perform an up-the-ladder false cut to bring the stack back to the top.
I follow up with a false shuffle (Artanis shuffle) and then deal out the poker hands.
