Moving to the army at hand, I'll go ahead and negate your pesky Marro Plague
Marro Hive - 160
Marro Drones x5, 250
Atlaga - 90
Total, 500 points, 17 figures, 22 hexes
My 15 Drones should easily outmaneuver your 6 hounds, and if they ever do get caught at least they are immune to the plague. Without a screen, the drones should be able to overhwhelm Q9 although of course the Queglix gun will be difficult. But I have the spare figures to lose a few and eventually I should get a large enough activation roll for the Drones that Q9 won't be able to stop the onslaught. If somehow this doesn't work, I still have a 25% chance at an insta-win with Bolt of Witherwood
