Maxello Magic

A deck of cards is shown to be in no special order. The magician takes all the picture cards from it in a separate stack and starts showing them two by two.

They never match, neither in value nor in color. When the magician wants, they all appear to be in matching couples (e.g. Jack of hearts and Jack of diamonds). The rest of the deck can be shuffled by a spectator and the same thing will happen with every single couple (e.g. 10 of clubs and ten of spades, etc., etc.).
