Personally, I'm playing around with idea of Power Field Generators from Dark Angels (although more as a thought experiment)
-You can get 2 since you're allowed 1 HQ and 1 Techmarine (doesn't use an HQ slot)
-You can affect multiple squads with 1 PFG
-Librarians are cheap and have Fearless (unfortunately Techmarines don't)
-Imagine a Techmarine on a bike with a servo-harness and PFG following a squad of Leman Russes - AV 14, regenerating, 4+ invuln madness
-Azrael is even better since the invuln only goes to his unit
-Priests will let you re-roll that invuln save in combat, so who cares if it ends up extending to your opponent; the math is still on your side

I'd actually consider taking Dark Angels as the Primary
-You can fit a ton of bodies into one platoon and deploy as multiple squads
-You can take up to 4 PFG's, which is only really useful in large games
-Azrael gets to choose his Warlord trait, so you could have a 50-man blob with 4+ invuln, FNP near objectives, and Fearless. Throw in priest(s) for more cheese
-Azrael also unlocks Ravenwing and Deathwing troops in Primary detachments only
