This post will slowly become more relevant to the
Chamber of Mazarbul... I promise...Please bear with me...
I started collecting
TLotRTCG when it first appeared, but "capped" my collection at the first card of Shadows. So I only own (nearly all of) the first ten sets plus a card from set 11. Most of the friends I play against use cards from my collection.
We like Reflections and we like the Weta Promos released prior to Shadows (maybe others too if I get hold of them).
We don't like being told we can't use cards (that good money's been paid for).
We usually play with cards from sets 1-10 and King Sites (plus those Weta promos and
11R1). We sometimes cap the allowable sets and use the relevant sites (at the moment I'm teaching my girlfriend to play using cards from set 1 only). Whichever "format" we play, we use text from the same relatively short list of errata to "replace" the text on the relevant cards (most of which were officially X-listed).
Ah! The relevancy at last!
Here's the first bunch for your perusal. More will follow. Please note, everything is the same as the original card except the title and game-text. (O) denotes an official erratum; (H) denotes a house erratum. Sorry I haven't yet learnt the keyboard acrobatics to make these prettier...
1 U 12 *Gimli ~ Dwarf of Erebor (O)Damage +1.Fellowship: If the twilight pool has fewer than 2 twilight tokens, add
2 to place a card from hand beneath your draw deck.
1 R 40 *Elrond ~ Lord of Rivendell (H)To play, spot Gandalf or an Elf.
At the start of each of your turns, you may exert Elrond to heal every other ally whose home is site 3.
Fellowship: Exert Elrond twice to draw a card.
1 C 43 *Far-seeing Eyes (O)Plays to your support area. Each time you play an Elf, choose an opponent to discard a card from hand.
1 R 45 *Galadriel ~ Lady of Light (H)To play, spot Aragorn or an Elf.
At the start of each of your turns, you may exert Galadriel to heal every other ally whose home is site 6.
Fellowship: Exert Galadriel to play an Elf. That Elf's twilight cost is -2.
1 U 46 *Gift of Boats (O)To play, exert an Elf ally. Plays to your support area.
When the fellowship moves from a river during the fellowship phase, the move limit for this turn is +1.
1 R 50 *Legolas ~ Greenleaf (H) New erratum, currently under playtest 
Archer.Archery: If you can spot more minions than wounds on Legolas, exert Legolas to wound a minion. Legolas does not add to the fellowship archery total.
1 R 55 *The Mirror of Galadriel (O)Plays to your support area. Each ally whose home is site 6 is strength +1.
Manoeuvre: If an opponent has at least 7 cards in hand, exert Galadriel to look at 2 of those cards at random. Discard one card and replace the other.
If you cannot look at a Shadow player's hand, the effect of the above special ability is ignored.
1 R 80 *Ottar ~ Man of Laketown (H)To play, spot Gandalf.
Fellowship: Exert
Ottar and discard 2 cards from hand to draw a card.
1 U 108 No Stranger to the Shadows (H)Bearer must be Aragorn or Faramir. Bearer must be a ranger. Limit 1 per bearer.
Each time the fellowship moves, you may spot a minion to remove
1.
