I'm not sure I have the player aid card. I have a rulebook, with on the back of it is kind of a player aid, bit it's turn sequence stuff only. I also have the cover that came in the bag, that has the unit info on the back and identifies the counters and the numbers on the front, but doesn't say anything about what the number means when it's spent.
The unit information on the back of the cover is what I meant when I said player aid card, sorry. I wasn't sure if it had anything about the number on the spent side.
All sorted out now anyway!
