Ok, I just don’t get these two cards.
Bistan is unique, faction-locked to Rebels and allows you to make a turret attack against a ship you haven’t yet attacked this round, but only if you’re focused.
VTG gives you a bonus attack from a turret you haven’t used yet in this round.
Both of them happen after primary attacks. But Bistan is far more expensive, despite being far more restricted. What gives? When is Bistan ever better than VTG?
