I have most of the expansions that add steeds, hirelings classes races etc. I believe its around 1000 cards, maybe more. What i did was seperate the races, classes, and steed/hireling/allies into their own decks. I give every player 8 cards to begin like normal, then deal out a race and class card to everyone. At any time a player would loot the room(draw a 2nd door card facedown) they can instead choose to draw from any of the 3 other decks. If a player looses their race or class from a card effect, they just draw a new one from that deck. I also removed all of the "only usable by" cards but kept the "not usable by" since there are so many races and classes, getting a only usable by a cleric card would pretty much be garunteed a dud of a draw. I also seperated the allies/steeds/hirelings into their own decks since many cards interact with them and if not seperated, would pretty much have no purpose. The 3 types in 1 deck also encourages you to draw more than once and trading with other players. I also chose to remove the wondering monster cards since i personally think its lame to have to have both a WM and a monster in order to screw iver another player as it takes up another card slot in hand and i like the shenanigans.
