Here you go. 1 coin rep. Mk1 battleships with aurora. Dom (yes, it's mk5, but this works with mk1) with spectre squads. Works with a rag but you'll take more damage.
That's the best way i've found. There are some ways to even do it without taking any damage but those require the Ranger swarm.
For these fleets dooes agression change the starting position of the player fleet?
