Drop the illegal Scimitars, and the Threatening and
Vicious Warg's. They are overkill without the kill.
Orkish Invader is your best wounding option, because FP player's will waste their goodies on him. His strength means he is not often the weakest minion so he misses
Ranger's Longbow.
So that means conditions.
Coordinated Effort is probably your best bet,
Destroyers and Usurpers or
Beasts of Burden being really the only other options.
With a mad cycling FP you could run the twilight Orc's, Runner, Scout etc and use
Mountain-troll for a swarm at the right moment. Maybe not a viable option.
