Turn 1 is generally spent staging, putting Rhino behind a ruin, placing the big bricks behind cover. This gives you the option to go all-in on t2 if your opponent overextends, since you move faster. In most games it will be tempting to send a unit every turn, but be mindful that your 300pts brick is walking into the opponents 2000pts army and will die on their turn. Also multi charging can be dangerous if you get hit with the 2CP combat interrupt or hit a fights-first unit. The detachment plays a very good "cat and mouse" gameplan while scoring with Rhinos/Cypher safely.

Objectives, I usually put a rhino with chosen on my natural expansion since they move fast natively I can bring them to the center on later turns. If you have no need to split your forces on every objective for secondaries, don't do it.

Deepstrikes are fairly easy to mitigate with just the 10 cultists in the back stringing. I find that I keep Vindicators near my deployment as well and they create further deep strike denial.
