List is designed to be extremely shooty with all the Psycannons. Take advantage of maximum distance and the shrouding as long as possible and target all things that can hurt your crusader first. Hide your crusader unless they have minimal weapons that can hurt it. Escalation is favorable because of the same reason. If they don't have much anti-tank (rare) deploy one squad of terms inside and go right at them. Some games my Crusader has owned the opposing player after having disposed of all his anti tank weaponry and against Nids it does extremely well staying mobile and shooting.
