The Empire is missing a bunch of really good pilots in Hyperspace right now, so I’m having to reach farther and farther to take reliable lists. This is pure theory - I haven’t actually flown this yet.
Pretty much, the goal is to joust Countdown against the strongest lone ship your opponent has, because his ability will always prevent him from taking more than one damage. Fifth Brother and Targeting Computer really help with dice mods.
One he strips a bunch of shields, Maarek and Gideon can start punishing your opponent. Vermeil is mostly there for fire support and maybe as a distraction. Krennic adds a lock, which is helpful.
Main list: (194)
Maarek Stele (45) {53}
•Fire-Control System (2)

Major Vermeil (49) {53}
•Director Krennic (4)
