a few months before when i was more active on gccg i remember to face a Cirith Troll deck. It was quite fun since it was bassically A LOT of cheap support area possessions (and grond of course), shelob, some cheap sauron orcs (that reduce site or roaming penality) and the troll.
It lose badly to decks that can blast the troll before he fights, but shelob was also very dangerous with that gollum condition that discard to make her st+1 for each culture you can spot. So it was basically designed to kill decks that doesn't kill at man or arch or at least stop from doubling with shelob... Not the best ever but it was a funny deck that can turns into a big problem at least sites...
