Deploy as one block, not two. The instinct with a machine list is to spread the war engines for firing angles. Resist it. A tank 8 inches from your Sorcerer is a materially worse tank, and a robot unit 14 inches away has lost its Weapon Skill bonus and both of its stratagems.
Put Walking Rampart on the Sorcerer who leads the advance. Its Kine-shielded Guardians clause gives that model Lone Operative while within 3 inches of a Sekhetar Robots unit, which makes the single most important model in your list effectively untargetable at range. In a pairing where losing one character degrades your vehicles, your robots and two stratagems simultaneously, that protection is the most valuable 30 points on the table. The D3+1 repair is a bonus.
Put Occulus Infernum on a second Sorcerer. It gives a robot unit +1 BS until the start of your next turn, which is the shooting fix neither detachment rule provides, and it means your second character has a job rather than just being a spare aura.
Spend the re-rolls on one activation, not spread thin. Warpfire Infusion's three re-rolls are per unit, per shooting or fighting activation. Their value is highest on your single biggest gun against your opponent's most important target, because fixing a Hit, then a Wound, then a Damage roll on the same attack is how you guarantee the shot that matters lands end to end.
Remember what neither detachment gives you. Neither adds Objective Control beyond Arcane Venting, and neither adds bodies. Bring Rubric Marines to hold ground, because a list of expensive machines and two Sorcerers can win every firefight and still lose on primary.
