Hi guys.

just looking for how this works exactly when she is undocking from the ghost. Obviously she can't barrel roll before maneuvering, but can she boost, using the ghosts rear guides as a starting point, or, does she not get to use her ability the turn in which she undocks?

Tournament tomorrow, would like to know how it goes before I get surprised there haha

When you deploy you are not revealing your dial. You are choosing a maneuver. Also since the ship is not on the playing area until after the deploy maneuver, there is no way for it to use its ability.
