One thing i’ve been thinking of is instead of taking him on with shootin I can take him on the fight phase. I’ve nearly got this list ready:
It honestly looks like a very jumped and disorganized list to be honest. Not a terrible amount of synergy, more a reliance on splitting your forces up and hoping they can do enough damage.
In this list Guilliman is potentially easy pickings. Unless I'm mistaken, he can't be embarked in a transport and there are no troops near him to provide him some cover from incoming fire. (Yeah you have the land raider as some protection, but that forces you to slow it down to keep up with him and potentially soak up even more firepower.
Chronus / Landraider Crusader - Hurricane bolters / assault cannon / multi Melta - 370
Keep in mind that as per chapter approved Chronus is 5 points more expensive than listed in the codex.
I get that Tiggy here provides you the null zone bubble, but you can do that for fewer points with a normal or primaris librarian.
Scout - Bolters - 55
Scout - 55
Scout - 55
These guys feel more like a command point tax and are more a waste than anything. That means your effectively going into 2k games with an 1850 list.
Stormraven - twin lascannon / twin heavy Bolter / 2 x Hurricane Bolters / stormstrike missiles - : - 300
Beyond an expensive delivery system, again I'm not seeing loads of synergy here.
Ironclad Dreadnaught - Chainfist / combat weapon / melta gun / stormbolter - 145
Low cost and a decent close combat output, I'd actually suggest running him alongside Guilliman.
Assault Terminators / Hammers / Shields- 235
I recommend keeping two with lightning claws.
I'd recommend giving the following some thought:
