1850 Dark eldar, with Imperial guard formation

Hi. I want to try using imperial guard artillery to counter our lack of long range blast weapons.

Here is my list

Formation: Grotesquerie

Haemy 70

Formation: Emperor's Wrath Artillery Company

Basilisk 125

Deathstrike, heavy bolter 160

chimera 65
4X veteran




Point is, I don't know Imperial guards well enough to design efficients squads, but it's still something.

My strategy will be to castle my tanks, with a grotesquerie raider near, with the haemy as leader.
I will charge with my succubus and grots, but will stay relatively passive, while my basilisk will strike.
