This is a very clever and strong "matching effect," with a double whammy climax. The performer displays 2 sets of 13 animal cards. There are duplicates of every animal in both piles. A spectator is asked to select any card in one pile, face down. There is absolutely no force, and the selection is completely free. The selected card is placed crosswise in the pile, to mark it. The performer now turns over a card from each pile, one at a time. The pairs do not match. When he comes to the selected card he places this aside, with the corresponding card from the other pile, face down. After all the cards have been dealt, (and none of the pairs match), the selected card and its mate are turned over. They are a perfect match. That's climax Number One. Now both the piles are turned over face down. They are tapped with the selected card pair, and then again turned face up, one from each pile. And now every pair is a perfect match - A stunning second climax!
