One idea which I am borrowing from Paul Phillips is that, if you are in a spot where the math says you should bluff 25% of the time, you can look at your watch and bluff if the second hand is between 1 and 15. You are on your own in determining which way.

Of course, this makes looking at your watch a possible tell, but the whole point is that you make random decisions, not that you use key cards to make random decisions for you. Certainly, cards are useful, but they are not the only thing you can use. If you wanted, you could base it on the the letters in the next word out of someone's mouth at the table. You could use a generate a random string of numbers and memorize it and use the digits of that number to form the basis for your random decision making. Of course those would be more work than necessary, but if you are not imaginative enough to come up with your own method that doesn't require cards and can only play as you are told, then you arguably don't deserve to advance beyond a certain point in your poker abilities.
