I thought about Terminators, or even taking two big Assault Squads and combat-squadding one so I didn't auto-lose, but then it isn't as fun. Plus the Intervention formation gives free S4 hits when it arrives from Reserves.

Does arriving via Deep Strike count as using Jump Packs in the Movement phase? If not, then it would be S4 Meteoric Impact hits, Hammer of Wrath hits and then assault.
