How can I make a Crisis game go faster?
I know that this is an old question, but how about this suggestion?

The main complaint that I am reading here is that the crisis and villain stacks are too large for a normal paced game. How about cutting all stacks in half, or maybe just the crisis, villain, and main deck in half?

In a normal game (non Crisis), we do not see every card in the main deck. By the time we are about half way through the deck, someone has culled their deck enough to kill the super villain every or every other turn. 

For Crisis, if you simply remove half of the main deck after shuffling, and half of the rest of the cards, then the game should be just a difficult, but will be faster.

When we do Crisis, it is a lot of luck. If we get stuck with something that requires everyone to destroy a defense or attack card at the same time, then we could go through half of the deck before we see another defense card. Then we need to wait for the player without one to get enough power to purchase it. Then we need to wait for that player to go through their deck and draw it. Removing half of the deck would not reduce this luck factor, and could help speed up the clock for those games where you just had bad luck with the randomizing of Crisis cards.
