Looks fun! Just a suggestion for the second option, you could replace the
IH CM with Shrike. Saves points, actually is stronger defensively overall (unit stealth + infiltrate will make a big difference to the enemy's shooting) and depending on what you're facing in combat is actually stronger offensively than the
CM anyway, particularly against the kinds of things ASM should be facing. You can infiltrate Shrike, Librarian, Blood Priest and 10 scoring ASM right into the heart of the enemy. Worst case scenario, you get first turn and finish your move 1" away (if you want) from an enemy of your choice and get to flame/melta it, pistol it + librarian zap it. Best case scenario, you start in cover 12" away, cop a round of shooting in cover with stealth and
FNP, then charge, shoot and bring the pain to any unit you want. I think Shrike's benefits would be greater than the
IH CM. You could always put the libby in another squad if you don't want to put all your eggs in one basket, but especially if you have some good defensive powers or short range powers like those from telepathy/divination, he could be a game changer when infiltrated too.
Anyway, love the idea. I wouldn't say it'll be heaps competitive, but you said you're not worried about that anyway. I definitely think you'll be in trouble if they bring in any kind of air (like... you pretty much have nothing unless they're hovering) and I don't think you'll get to apply the hurt until turn 2-3, which gives them time to get their air in. I'd say you could still do with a little more
AT too, but as long as you have meltas in your ASM squads to combine with the
MB, you'll be okay. Last thing is the scouts, why bolters? What are they gonna do? I'd say just give 'em snipers, sit 'em in a building and hope they can pin something at some point.
Good luck man! If you play a game, let us know how it goes
