&lt;h1&gt;&lt;font color=&quot;#0000ff&quot;&gt;Rainbow Deck&lt;/font&gt;&lt;/h1&gt;&lt;h2&gt;&lt;br&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;Colourful Mental Prediction~Different Card Backs&lt;/span&gt;&lt;/div&gt;&lt;/h2&gt;&lt;h2&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;The magician displays a deck of cards.&amp;nbsp; The cards are different from a normal deck, because all the backs are different. Magician removes two cards from the deck placing them face up on the table.&amp;nbsp; Two spectators introduce the cards into the deck at positions they select.&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;&lt;br&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;The magician removes the face up cards and the cards just above them. The pairs are found to be a perfect match for value and colour.&amp;nbsp; For example if&amp;nbsp; the face up card was five of Clubs, the face down card is five of&amp;nbsp; Spades.&amp;nbsp; Then he turns both the cards in each pair face down and the backs match perfectly, although all the other cards have different backs with no other duplicates.&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;&lt;br&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;And for a final climax, the rest of the deck is turned face up and ribbon spread on the table.&amp;nbsp; All the cards are found to be identical, and different to the two pairs.&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;&lt;br&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: inherit; font-family: inherit;&quot;&gt;Supplied complete with the very special deck, and instructions, the trick almost works itself.&lt;/span&gt;&lt;/div&gt;&lt;/h2&gt;
