I no longer work for IELLO.
You discard you whole deck and draw a madness card. Do you get to redraw? Rules say you draw at the end of your turn, but then this card would practically be a you lose the round card.No, you don't redraw. But you discard only your draw pile, not your hand or Support. And you don't "draw" a Madness card: you add one to your discard pile the next time you need to draw, following normal rules (as your draw pile is now empty).
