Step by step
Take your ESP deck that is in standard setup - 5 ESP cards in order that is repeated thru entire packet
Shuffle the deck in a way that this order is not disturbed (tutorial here), you cal also ask spectator to cut the deck
Spread cards in front of spectator and ask him to choose a card
Place this card face down on the table - separate the deck into two piles on a place where spectator selected the card and place the top packet to the bottom (please see video below for details)
Divide cards into two piles and place them on the table - reverse order of first 12 cards by counting them one by one on the table, order of rest of the cards can't be reversed so you can just count it in your hands if you want
Start turning over top cards of this two piles - search for matching pairs
You'll always have matching symbols on 3rd and 8th position
Reveal that the card that was freely selected by spectator is matching the symbols you found in the deck
