thran is correct about not being broken, but probably the closest to it is the
SftF/ninja gollum combo. if you have smeagol in your starting fellowship, burn hum with
SftF and pick up 3x
little snuffler. if you have any luck, you'll already have one in hand before that, and you end up with gollom dishing out 4 wounds at site 2 which means the ring-bearer might die. or at least, somebody will. it's a good surprise to spring and screw-up your opponent's synergy. noone expects to lose a key companion at site 2.
