Fire lord Azula and Chameleon Master of Disguise

If I copy [[Fire Lord Azula]] with [[Chameleon, master of Disguise]] does chameleon also trigger spell copying as well if I attack with just Azula since the trigger is based off her attacking? Also, would he even trigger spell copying if I attack solo with him since I’m not sure if it overwrites the text with his own name after the copy.
