I had some success during some recent sessions where my opponents fielded phantoms.
My list:
Boba Fett 39
Veteran Instincts 1
Navigator 3
Engine Upgrade 4
Prox Mine 3
Kath Scarlet 38
VI 1
Nav 3
EU 4
Prox mine 3
Let the phantoms move, adjust your dials and boost into arc then open fire before they can decloak. A 2 agility phantom isn't hard to take down. In fact I was able to avoid it's arc quite often.
