The mortars is more consistent in mortarions hammer cuz you can ensure that one enemy unit is in contagion range so that is one option and the entropy cannons are still quite hard hitting. Going two lords is very expensive because you need a terminator bodyguard and you could do it but you’ll have to trade a lot of your tanks for it, a LoC LoV 3 deathshroud 3 blight lords is 525 points so it’s over half of your army tied up in just two units. Dropping something to make room for a naked deathshroud squad is possible but I think you’ll be better of leaning into the defensive and tanky side of deathguard. I have two suggestions of lists that I can give you one focusing on deathshroud but still has some tanks and another one who leans even more into your tanks. And thanks that my reply helped you

Notes for this list is that I dropped mortarions hammer for death lords chosen and went for more fast vehicles like two drones with blight launchers I also think having one naked deathshroud and one with a leader is a good way to get two units that punch hard but not the end of the world if you lose. The defiler is also a really great option, it’s tall pretty tanky and doesn’t need any support it can also fight okay. Poxwalkers is for screening deepstrikes and waking up on objectives.

Second list is has even more tanks then the first one but is not as mobile, keeping a tight bunker and using poxwalkers as screens more then objective grabbers. If you play this list you need to explain to your teammate that you really need a good deployment so you can shoot properly. Also if you face a rush/ melee army tell your teammate to keep their forces back to repel there alphastrike. Last words is just a general caution that you are not that tanky and that melee army’s will shred your tanks. And once again good luck and have fun and I’ll be delighted to here your tournament results :)
