As a newer player (and LCG only), I was curious about faction combos. I noticed that most decks (competitive or otherwise) seem to be dual faction. At the moment, are there any factions that can stand decently (or even well) on their own? While not adverse to dual color / faction / etc. decks, I generally prefer mono. Is such a thing feasible at this point in time?
Cthulhu seems a candidate, but being new, I could be wrong.
