Tactically, I think this for the most part is pretty obvious. Go punch things with Dreadnoughts. But there are a few subleties.
First of all, the Mortis and Deredo pait up and stay together. Ranged firebase with an I save from the Deredo's Atomantic Pavaise. I may switch the heavy bolters to auto cannons on the Mortis (dropping magna grapples and a heavy flamer someplace to do it) BUT for now that heavy 12 is nice.
The Fragioso in the past was the clear choice to put into a drop pod, but the new 9" deep strike rules rule that out. SOOOO instead, he is a very situational beast. Most often plan is to leave him in my backfield, relatively close to my firebase, as a sweeper if you will. He is my ANTI Deepstriker now. And for people without DS, I'll just march him forward with my attack force.
The Leviathan is the NEW candidate for the Lucius Pattern Drop Pod. Big tough guy with the ability to take down most vehicles in a single turn with his cyclonic lance and storm cannon and tough to wipe out in return. Plus, just such a COOOOL model.
Main attack force consists of the Chaplain and 2 DC dreads in one group and the Librarian, Contemptor and Furioso in another. Run forward and tear things apart. The Chaplain and DC dreads are for attacking higher model count, weaker targets while the Lib and crew go after smaller, tougher nuts to crack (all ideally)
Chaplain is the Warlord OVER the Librarian for two reasons
1- He comes with an Invulnerable Save
2- I can give him soul warden, giving him the ability to deny the which IN ADDITION to having that naturally in my Librarian dread.
3- If he is primarily chasing infantry, he is less likely to encounter things that can hurt him.
Over all, it just seems FUN and fluffy to do, so I want to make it happen.
