New events and the return of any one-off mechanic other than Potions is always welcome to me.
I'm hoping for more $+debt cards like Fortune, it could be fun to Remodel Engineer into a 4 debt+$2 value card.
"Shadow" though? Is full deck searching to grab cards now a thing? Different backs like Stash to make finding them easier?
25 kingdom piles is already 275 cards minimum. Previous Event sets have had 13-20. I expect there's one 1-count Victory card, so lets say 277 Kingdom cards. If Prophecies are Environment-style cards, I'd guess that 10-13 are those, with the Events rounding out the stack with 10-13 of them. If Prophecies are mini-game-like action/treasure cards (akin to Magic Lamp, Haunted Mirror, or Leprechaun) then they would already be accounted fors. They might be mini-game events (or Event-likes) akin to Windfall. I look forward to previews, and hope for a hype trickle, unlike everything dropping at once in the Cornucopia/Guilds rulebook.
