Mental Fooler is a great and direct effect. It looks like you really know how to read the spectator's mind. The most important element is that you can do this with a borrowed shuffled deck. Everything is done with the cards face down. You take a borrowed deck of cards and remove a couple of cards. While you are turned away the spectator first shuffles these cards and then only thinks of one of them. Then you explain to him how to spell a card and move for each character a card from top to bottom. While you are again turned away the spectator spells the thought of card silently. You are able to determine which card the spectator is thinking of. No gimmick. No peek, just a bit of sleight-of-hand and memorization.
