Even if a square is filled by SVs(so the size point is 6) and a missile can always hit the square accurately, there is only 4.5% chance to hit anyone( (size 6 + attacker DRN vs 2+shield parry 4*2 + defender DRN)*25%). Considering twist fate, the damage is almost negligible. With flame arrow, the chance to hit will be increased to 30% so missile fire will be much more effective. If Machaka has reached Enc-4, maybe he can outnumber those ethereal maiden with cheap archers.

IMO an easier way is mass death mage and spamming dust to dust. Killing 3 twist-fated SVs with 2 casting is quite acceptable(Solar ray has better range but Machaka doesn't have any astral mage). You may need 10+ death mages and sevaral priests to make sure you can kill them fast enough if your enemy mixes SVs and undead horsemen. But Machaka has 3 forts so I think it's not too hard for him...
