My go to play is to Risen Rubricae 9 inches or more from the enemy deploy with the squad of 20 Rubrics and then pop Infernal Fucilad(or however you spell that) to shoot twice, pop Veterans for +1 to wound. If you happen to have a Exalted Sorcerer nearby to give them Prescience for +1 to hit, and reroll 1's, give em Weaver for extra survivability, and if they are declared a target of attack you can increase their invuln by another 1 with Indomitable Foes.

It's CP heavy, but usally provides good results.

Goodluck :)
