Has anyone played Time Travelers and Elder Things?
I don't mean to be hyperbolic here, but the amount of Madness card recursion with these two decks is, excuse the expression, insane.
Once these decks get rolling you can quite actually run out of Madness cards (luckily we own two copies of the Obligatory so we've got quite the pile of Madness.) If you haven't tried it out yet, do yourself a favour and watch the Madness unravel.
Wow yeah I didn't realize the power of that combo. That would be pretty miserable to play against. Constantly replaying Byakhees and the one that forces your opponent to pick up two madness cards would be so frustrating. I just feel that it would take forever for you to win the game since everyone would just waste their turns returning madness cards. Wizards and Miskatonic might stand a chance though.
