i will go with some decks :
this is the top of the top of creative decks :
http://www.decktech.net/lotr/decks/decks.php?deck=33930a deck with million combos inside,in the hands of an expert (and only expert player) this deck had 99% of winning.
also
b) a discard deck i saw in official lotr online tcg with melon.
c ) shadow side with million of possessions playing in support area and a couple of uruks+sauron trolls etc
d ) a deck with gimli ringbearer (with ring of hunter3), isildur (with 1 res) faramir (hunter 2,exert to heal) aragorn (hunter 2 , exert to exert ) and gandalf , with quite a lot of combos and answers to everything.For the three hunters , cool healing , blood runs chills, possessions removal,strong companions etc )
e) 4 hobbits - cheap frodo,sam that sees hobbits to get pumped ,
wobas pippin and
merry friend to sam,
smeagol always helps : initiative abuse +
shire countryside + choke .
ps : i hate solo decks ,at least when i used to play against cause i never liked to be chocked.I have seen frodo,smeagol,sam,galadriel solo.
(i am quite sure i have met more decks that were very creative but dont ring a bell)
