One-Way Deck
Keep an eye on the person to make sure he doesn't turn his card around.
Preparation
1. Take a deck of cards whose back is not symetrical (the picture looks different upside down) and line them up so they all face the same direction.
Performance
1. Shuffle the deck, being careful to keep the backs facing the same way.
2. Fan the deck out and ask someone to take a card.
3. Turn the deck around and ask the person to put his card back in.
4. Shuffle the deck again once or twice. Look through the deck and find his card.(It will be the one facing the other way.)
To make the card trick less obvious, look for cheap cards that are supposed to be symetrical but aren't. Arrange them so the fat margins are on one side, and the thin ones are on the other. You can also mark the corner with a pen (same color as the backing).
