IF ONLY I had a plan...
The lesser of two evils?
Honestly though, you are usually better hoarding those for the next crisis as it is usually quite hard to meet a crisis and then have stuff spare.
Actually, I believe that depends a lot on the number of players. If you've got a 5 player game, 2 cards for an extra Morale is a great deal since you might be able to save 5 cards on a later Crisis. In a 3 player game, the value is a bit less.
