When they are all up I will tell you the context in which they were first used, but ther is no real doctrine about where or when. Just use them for any scenario where you envisage they may be useful. For instance the shoals ones are only any good if you are using shoals. On the otherhand you can use the Captain casualty whenever the Ares rule for Captain being hit comes into action. If you have a look at the last couple of years solo Campaign games you will see where I used some of the sets of cards.
