All life is only a set of pictures in the brain, among which there is no difference betwixt those born of real things and those born of inward dreamings, and no cause to value the one above the other.
I have a situation: all AI spent but player has a some fresh units. Should AI draw new card after each players turn (maybe Command Card will be drawn) or passed?
Always draw a card. The mission track might still advance even if the AI passes its turn or, as you mentioned, the AI might draw a Command Card.
