At this point level, an archon with blaster, haywire grenades, and maybe some Armour like the clone field or Armour of misery. Put him in a venom with 2 cannons and call it good. You could also just do a Lhamean in a venom too and save points. From there, I would add some warrior venoms with blasters and a ravager with lances. It . Shooty only army, but will be effective.
A second option, with a bit more versatility would be 4 Sslyth and 1 Lhamean in a venom with 2 cannons. Warrior troops with blasters in venoms (make one a sybarite with haywire grenade to get warlord) and a ravage with lances. Sslyth are good at shooting and not bad at assault, especially at this point level. Hope this helps
