Question. What do you do when this happens?
I am not going to go into the maths but it is not as unlikely as it sounds.
Example . X6 bomber squad 36 hull points possible future hull upgrade card also.
Theoretically if all double damage crit cards were received face down then you have a shortfall of three cards, that's without taking the over damage cards.
There are other ways but it doesnt matter, one is enough
