I use him to stack nearly all minions, so they can start to swarm at site 7+. Sadly, the Besiegerswarm is a late FP Killer.
He is good for
Troop Tower and
Ologhai of Mordor, so the Trolls come out at site 5 or so, for free!! And with
Beaten back,
Din of Arms, and
Tower Walkway,
Ologhai of Mordor are not that weak, even for Fellowships nowadays.
Oh, and they make even more minions. The thing is, that
Gorgoroth troop is expensive, cost 8 if roaming. So there is not much twilight left for other minions to play, which you want to stack at early sites.
Eats a whole troop even...


Is this for a convuluted deck?
What does convulute mean?
To be sure:
Troll of Gorgoroth stacks himself too, right?
