Now according to the second part of rage of the Matsu:
Tactical Battle: Target a Personality in his controller's home. Move him into the current defending army. If he moved, straighten his unit
now if i am defending and the attacker has someone at home, using this the way it is worded i should be able to bring that peronality into my army because i am defending. i have been told that i cannot because i am not his controller, but according to the wording i do not have to be the controller if i am the defending army, just as long as the personality is in his controllers home when i play this action. Is this correct? or just bad wording?
