I think he would likely just allow his unit to deep strike T1 or T2 without scatter.
He would have AP3 powerblades, and a twin-linked AP2 death spinner. Plasma grenades too, if you're really lucky.
Iron Discipline is kind of useless, as he would be fearless, so he would have an ability that works in challenges instead, like gains Shred in first round of challenge, etc.
The other one that would be great is a Shining Spear phoenix lord:
star lance, hit & run, and allows spears to charge on the turn they outflank. Bam!
Ideally he would have plasma grenades too, but here's to hoping.
