One other note:
I consider Unity and Sky-scraper an excellent team up. Unity can blow up links to play Golems. If she can get Stealthbot out, Sky-scraper doesn’t need to worry about hitting heroes (unless she has a damage boost from an external source). Cryobot can take damage from Sky-scraper’s area attacks to inflict even more damage on non-hero targets. On turns where Unity has no Golem’s in hand she can make great use of Micro-assembler. Lastly, Thorathian Monolith plus Hasty Augmentation makes for a very nice attack.
