My gaming groups (or gaming duo's) are always pretty casual, and not inductive to people building their own decks. So I liked the mix and match ability of the core game, and I wanted to continue it on with the expansions. I decided to break factions into sets of 20 or 10, and, for the most part, keep the themes of the different cycles and packs together as much as possible. I named the Decks by the origin of the majority of the cards in the deck, Included a conspiracy in each Neutral Deck, and name those decks by that card. I didn't worry to much if an some of the individual modules where unbalanced, as other modules could balance them out, and some people might look for that particular type of unbalance. So far I have included cards from the Core game, the Mountains of Madness(MoM) pack, the Ancient Horrors(AH) pack, and the Summons of the Deep(SotD) packs.
I know that these module decks aren't usually going to compete well against a completely built deck, but so far they allow me to bring out the game much more often, and I find I experiment more with the combinations. I thought others might be interested in what I've put together, and, perhaps, suggest alternative groupings, or point out any bad combinations that I might be unaware of in the decks. All the decks are grouped next by faction, with the "20" decks before the "10" decks.
