Great way to represent his temporary power that could escape him at any time. Have you thought of just utilizing the Initiative roll to determine the power? It seems like you are rolling the 20-sided die twice at the start of the round when you could combine them into one roll. Of course you'd have the awkward realization that you are rooting to win initiative with a low roll. And I guess powers that affect initiative would potentially affect Hourman's power timing. Never mind.
Now if only someone could convince you to put a signature somewhere on your cards.
