I really like the Hastur faction, and I've combined it here with Cthulhu. The idea is to drive most of my opponent's characters insane, removing terror icons with Messenger from Beyond and Scotophobia. Victoria's Loft can keep them insane, while The Sirens of Hell and Wandering Inmate can remove them from play.
This deck is weak in the combat struggle, but I think it should be able to remove my opponent's combat characters in the terror struggle. Nightstalker and Sleep of Reason add terror struggles in an attempt to drive more characters insane. Opponent's willpower characters should be the first target for cards like Deep One Assault and Deep One Rising.
This is my first attempt at building a deck of my own, and I think this is a decent deck. But then again I haven't played this game a whole lot, so I could be wrong. I'm toying with the idea of switching out the Cthulhu faction for Shub-Niggurath, but I'd like some feedback on this one first. It only has 12 Cthulhu faction cards, so might it be a good idea to switch in some more, to make resourcing for Deep One Assault easier?
