Key Mechanic: Curse of Knowledge
Every cycle, the Demon forces you to choose between two Curse cards. The choices escalate in severity: Set 1 offers Disintegration (6 damage/turn) or Mind Rot (draw 1 fewer card). Set 2 offers Disintegration (7 damage/turn) or Sloth (max 3 cards/turn). Set 3 offers Disintegration (8 damage/turn) or Waste Away (1 less Energy/turn).

How to Beat Knowledge Demon
Speed is critical — every cycle adds another permanent Curse that weakens your deck. Choose Disintegration curses if your deck has healing or high HP, choose the other options if you can't afford the chip damage. Exhaust effects can remove Curses from your deck mid-fight. Front-load damage to end the fight before the third Curse set makes the run nearly unwinnable.
The Curse choices get worse each cycle — end the fight fast
Exhaust synergies can remove Curse cards from your deck during the fight
Disintegration deals damage every turn but doesn't limit your card play
The Ponder turn is your window to heal or set up — no damage incoming
