In order to perform the "Magical Morphing Jokers" trick, you will need a deck of cards with 4 Jokers. This trick proves that all Jokers want to be king. Show the 4 Kings. Place them in the following order: black-red-red-black.
Create a break: i.e. while holding the deck of cards in one hand, keep the Kings separate by placing a little bit of space between them and the rest of the deck. Separate out a black King from the deck underneath it. Create another break, by holding the other 3 kings aloft above it. Since this trick involves some slight of hand, the breaks should not be noticeable to your audience.
Show the 4 Jokers. They should be face up. Place the 4 Jokers on top of the 4 Kings. Then, lift up all 8 cards with your right hand. You should still be preserving the break. Show the 4 Jokers on top to your audience. You should still be holding the remainder of the deck in your other hand.
Peel off the 1st Joker and place it underneath the break. Repeat this with the second Joker. Now, drop your break on top of the rest of the deck. Peel off the 3rd Joker and place it under the 4th. Now, you can put the rest of the deck away. In your hand, you should be holding 2 Jokers with 3 kings between them.
Take the bottom Joker and put it back on the top. You will do an Elmsley Count for your audience: 1-2-3-4. You will be concealing the fact that you have 3 Kings and 2 Jokers in your hand. All of the Kings count as one. They will be face down. You will count one of the Jokers twice.
Create a break: a pinky break. Hide the bottom card. Place the face up Joker on the bottom. This time, when you do the count, you will be holding both Jokers as if they are one card, and you will count the 3 face down Kings in your count.
In your Elmsley Count, show the audience that both sides of the cards have backs showing. Now, slide the top card back to reveal that the card underneath it is a King. Then, do a final count to show that all 4 cards are now Kings.
