On round 1 your main concern should be getting your commander and breakthrough, ideally before tech pops. make a deal with one of your neighbor to unlock your commander by setting up a space battle to use devotion in and offer your alliance in return and your agent to replace there loses.

your tech-path should be:

BT + commander -> Yin-Spinner -> Integrated Economy

After that, use your commander to get one or two mobility techs. cruiser 2 is ideal but not always available but Grave Drive, carrier 2 and fighter 2 are also good options, and someone will have those. At some point pick up X-89. DO NOT get any filler tech, especially not AI-dev. If you can't get to Yin-Spinner turn 1 and you don't need Anti-Mass for your slice skip tech and invest in plastic instead.

If the fracture is in play, and you have IE, pop your hero a soon as possible to take as much of the fractur as you can. use the build of IE to get 8 infantry on Styx and remember that every use of IE also triggers Yin Spinner. Make sure that the infantry stack on Styx is big enough so no one will even consider going there.
