Does it works? Will it give her +3 move? Field Analysis wording says not +3 Initiative but +3 initiative for this comparison. Which intuitively means she will not have this bonus at the beginning of Action Step.
Short answer: no Long answer: no, because when Hippolyta gets the +X MP (at the beginning of her Actions Phase) Field Analysis is no longer active, so no +3, and no +3 MP Take note that Field Analysis works when revealing Initiative cards, and then is discarded an its Effect gone. :3
