ENIGMA
You have the Power of Ambiguity
Whenever you are the main player in a challenge, after cards are played but before they are revealed, you may collect a challenge card at random from any players not involved and mix them together with your opponent's card. You then hand them back randomly. Your opponent must now play the card he is given. He may look at the card, but he may not add a kicker (if one was already played, it remains). You do not mix your own card.
