Mandy keeps her deck in her Hand, Rogue Version

Deck based on Dream-Enhancing Serum and Laboratory Assistant to keep a copy of every non-asset card in your hand. As result you draw 3-4 additional cards earch turn and commit/ play the 2nd and 3rd copies.

The rogue version provides more ressources, while the survivor version is more consistent.

Basic strategy

• 2 Laboratory Assistants increase your hand size to 12. Dream-Enhancing Serum makes the 2nd and 3rd copy not counting against hand size.
• Get these assets into play as early as possible, while keeping the first copy of every non-asset in your hand to trigger Dream-Enhancing Serum's draw effect each turn
  • Mr. "Rook" and Eureka! help you locating above cards
  • Do not keep the first copy of Perception and Deduction on your hand, see additional combos
• Mandys of 5 means she doesn't need help investigating shroud 3 or lower on standard difficulty, so you can contribute to finishing the scenario from turn 1. You're free to commit cards beyond the first copy to tests.
• The deck's assets have a total cost of 18, so play other assets only if your Laboratory Assistants and Dream-Enhancing Serums are in play. Several of the rogue cards provide ressources, so for Astounding Revelation you're free to choose ressources or put more secrets on Mr. "Rook" to reassamble Three Aces or Pendant of the Queen
• Myriad cards work well with the Dream-Enhancing Serum cause the 2nd and 3rd copy don't count against your hand size and are more likely to trigger the serum's draw effect
• With all assets in play the deck has 11 unique cards (including Occult Evidence) so you could theoretically keep your whole deck in your hand, excluding weaknesses. However you'll take 1 horror each turn when reshuffling your empty deck.

Starting hand

• Dream-Enhancing Serum
• Laboratory Assistant
• Mr. "Rook" or Eureka! to search for the above

Additional combos

• Use Practice Makes Perfect and Mandys ability to find 2 of the following cards: Perception, Deduction, Three Aces
  • Don't keep any of these skills in your hand before your deck is reshuffled
  • Be sure at least 2 of these are in your deck before playing Practice Makes Perfect
• Dream Diary grants you a free skill card each turn with ??+?? because you'll have 8+ cards in your hand all the time
• Ancient Stone deals lots of damage with all the card draw
• Grisly Totem improves Essence of the Dream or other skills and provides more draw
