Powers on cards are not in affect after they are destroyed unless they state otherwise, so he cannot use the power once he is dead, otherwise Joker could reuse Organize Chaos after his death because you are allowed to still put order markers on destroyed cards (just not reveal them).
With that said, I considered the clear sight restriction, but I didn't like adding more text to the card, and I liked keeping him feeling Event like with his power level. I left off the Mental Shield restriction for the same reason.
