As far as the meta, Fellowship Block has a habit of changing in a constant, slow cycle. In general, you'll see twilight choke, archery, or Gandalf-centric Free Peoples (mainly pipeweed and
Trust Me As You Once Did) with Uruk-hai and
Saruman, KoI, Nazgul, discard, Sauron grind, or Moria Swarm shadow sides. When the choke gets bad Moria, grind, and discard strategies spring to up to punish their slow movement and expand the twilight pool. Archery and Gandalf take them down, so Uruk-hai and Nazgul come back to give those FP trouble, then choke makes a return until shadow sides swing back the other way.
This is a pretty broad simplification since that list isn't exhaustive and several strategies have their own cycle of counters, but that about sums it up. If you're looking for ideas for decks, this forum the best place to look.
