Can You Count?

A magic trick for every opportunity. Display four cards with red backs and four with blue backs. Place the red and blue decks on top of each other to create an aversion. A gentle puff of air transforms the cards into five red and three blue ones! Remove two red cards, leaving you with three red and three blue cards. Further shuffling results in four blue and two red cards. Discard two more blues, leaving just two: one red and one blue. You have eight genuine cards without any sleight or smoothing.

The detailed explanation of the trick will be provided along with the required eight cards.
