Let's say you have Ciena and some 1-hull remaining bombers inside an enemy firing arc.
Your opponent activates and choose to attack squadrons. He forgets Ciena skill and he declares he attacks her. He has just one die so the attack is canceled, he never reachs the step 6 so he cannot choose new target. He probably jump to your neck through the table but who cares?
Is it right? I mean, obviously it is easy to avoid and despite of that I am not going to be that man but it came to my mind and it seems funny to share with you and answer it btw.
