I read it but I still can't believe it
Yasuko's first ability:
Battle: Even if Yasuko is home: Target a Personality not at the current battlefield. Move him there. If you do not control him, straighten him.
Supposing Yasuko is home, can I declare an attack, not assign anything and then move one of my units to a battlefield where there are no defending units using the mentioned action?
