Strider/Illusion. A combination scout and saboteur. The key feature is the ability to swap your model for one in the enemy's color.

Krow is an air demi-strider (it's priced above the low tier striders even)

changing teamcolors of your units sounds hard against the Fight Your Opponent, Not The UI philosophy, like a-clicking zerg clones in starcraft 2 or pre-charging voidrays on eachother before killing a base.

Anyone remember when jugglenaught was a strider with like 4 forward facing gravity guns? a strider with placeholder blackholes and gravity guns and lobster launches sounds cool. But it needs to be more unique than 3 units glued together.
