Once you have Dathomir, start making Nightsisters and a space station to protect the planet. Destroy the space station and any spaceships after you corrupt the planet, then send your 'hired muscle' to destroy all resistance. This will allow you gain something extra on the battlefield. Once at Dathomir, make a Defiler and spread corruption on the planet. By doing this you will get more credits and a higher population limit. Capture any planets in your way and build palaces on all of them.
Then, fight your way to Dathomir no matter what the cost.
After creating a black market, buy the Buzz Droid upgrade and the Disrupter Rifle upgrade to make your forces all powerful. Then, create a black market on both Rebel and Empire planets. Make a fleet of StarViper squadrons, and a ground force of purely assault squads.
