What are the rules for the battles?
You do not need that many scoring troops
His honour guard are rubbish without cool upgrades.
He should have a second priest to maybe cover the scouts.
What models do you have?
What models does he have?
Vanilla troops are uninspiring and do not really fit so nicely with
BA. I would take Telion and then take a second token troop, then use the spare points to buy all sorts of cool stuff

, you have cool stuff
BA would love to have.
You should try abusing the
FOC as much as possible. Are you allowed 3 heavies each or 3 heavies in total.
So in general if
BA are going jet packs then you need to think about your role.
Maybe you should be the supporting fire power.
Or maybe you should be a drop pod army, as his scouts help and his jump packers come on 2nd turn to stop reserve shenanigans from the enemy.
Anyway post more rules about
FOC in particular and the models we get to choose from

, I am think about playing your troops as space wolves or Blood angels, seriously if there is a possibility of 3 squads of long fangs supporting jump packers sounds like fun, or even 6 squads of
BA dev. squads.
