Ok so i've analysed 20 draft packs. Here is some stats:
-At least 1 conspiration & 1 ancient one per factions (or similar big character cards on human factions)
-Between 2 to 9 cards per factions and between 6 to 9 neutral cards
-No duplicate cards in a draft pack
-Only found dreamlands wanderer in starter and draft pack
-Between 26 and 33 characters per draft pack
-With only 20 packs it's difficult to understand if there's probability/rarity but some cards (ancient or "powerful" cards) only appear once or twice when others can be quite common (like alaskan dog)
Few cards missing on your list (in white or grey in the file):
-Agency: Black Maria, The blackwood conspiracy, The Captain
-Cthulhu: Yig
-Hastur: Carcosa, In the court of the dragon, Sieur Piriou Louis
-Miskatonic: Jamie Winthrop
-Neutral: Pocket telescope, the supernal prism
-Shub: Shocking transformation
-Silver Twilight: Clifton Rosenberg, Initiate of Huang Hun, Magnus Stiles, Nigel St. James
-Syndicate: Immurment, La bella Luna, Richard Upton Pickman
-Yog: Ritual of Bellephar
Cards that i could'nt confirm in my packs:
-Norman Blackmoor Jr, Byakhee attack, Er'nrawr, The Claret Knight, Ya-te-veo, Satchel of the Void, Decrepit Wizard
Here is a complete list of cards in 20 packs: http://www.partage-f...upload/rw62albv
If we have around 50-100 packs we could do more accurate probability. I still need to improve the file with links to cardDB & more macro...
