Corran Horn: At the start of the activation phase you may perform one attack. You cannot attack again this round.
That's my guess.
That could be really good... don't know how i would feel about no token attack, but Advanced sensors will shine here basically giving you the attack version of Dark Curses ability. Here's it's best use in my mind...
Focus with Advanced Sensors
Attack with Pilot ability
4 K-Turn (assuming it has it)
It's very situational. The lack of being able to Focus means you may not want to use it every round. But it can also enable him to get one more shot at Soontir before he gets out of range, or take out a damaged ship or potential blocker before they can impede you.
