You could try my "Howl's Moving Castle" list:
Patrol Leader x2
Howlrunner + Swarm Tactics
You get to focus and reroll with your decis, and if Howl dies, you could always go back to target locking.
I do have 2 Decis.... I might have to try this.
You could also replace Howl's Swarm Tactics with a Tactical Jammer on each Decimator to make them moving asteroids so they wont shoot down Howl too early on.
