I have been thinking about Starborne lists that are more balanced, and not focused on the Troglodon bomb. Raptadon Chargers have a lot of damage output and could easily claim lightly guarded objectives. In Dracothion's Tail, beaming in a Troglodon, Starseer or Starpriest to an objective creates a Cosmic Node there. Cast some offensive or debuffing spells to soften the targets or provide defense against a counterstrike: Celestial Doom, Blazing Starlight, Primordial Mire, Celestial Deliverance, Comet's Call, Mystical Unforging and Stellar Tempest are all good candidates, depending on the situation.
From there you can summon units and/or pull them from reserve. At least one unit of Raptordon Chargers within 7" for the nearly guaranteed charge (at +1 to charge with their musician). A Spawn of Chotek if the target's a large unit, for Stream of Fire. Some skinks or Saurus Guard to screen and protect the wizard (remember that the Guard can absorb wounds for any non-monster hero now, so they can do that for the Starpriest and Starseer). Kroxigor Warspawned just behind the skinks can pile in and use their 2" range to counterstrike if the enemy chargers your skink screen, getting the +1 to attacks since the skinks would have just taken losses. If they get right up against the skink bases, they could even be in bite range of an enemy on the other side of the skinks. Even a Bastiladon with Ark of Sotek could join the fun if needed.
With Fangs of Sotek, there is no reserve (except chameleon skinks), so there's a lot more moving skink screens and skink calvary around the table. But they are masters of movement and can effectively block attacks with skinks and counterstrike with Kroxigor or Raptadon Chargers, all the while supported by powerful magic and Bastiladons with Solar Engines or Spawns of Chotec from behind the screens. They can still teleport wizards in and summon a unit to support their forces when they're about to move on objectives.
Everyone is very excited about the Trog Bomb, but these more balanced play styles could be very effective for Starborne, and you could still throw around a lot of spells and gather a lot of CPP to summon or heal your forces.
