When compared to a Black Squadron TIE fighter though...well things get a bit closer. With 1 less hull but 2 shields, the Phantom has an advantage of 1. In terms of attack, again a 3 vs. a 2, so the Phantom comes out ahead. Agility it loses but only by 1 to the TIE fighter. The action bars are identical so that is a push. The icon bar...they both have elite pilot however the system upgrade and crew member go to the Phantom. The Black Squadron TIE costs 14 points vs 20 for Ezra...so a 6 point difference in favor of the TIE fighter. Overall...I would say that the Phantom attack shuttle has a slight advantage in raw stats.
What is the purpose of the Phantom though?
How many rounds do you want to have one less attack available to you?
While in many respects the Phantom attack shuttle looks to be a potent addition...it has one glaring flaw while docked with the Ghost. Only time will tell how deadly the Phantom attack shuttle actually is.
