The text of the Wildling Wisewoman is:
Response: Kneel Wildling Wisewoman to cancel 1 card effect that would allow an opponent to draw 1 or more cards.
She can cancel the effects of cards as Bay of Ice or Samwell Tarly. But in the case of cards as Eddard Stark ( Response: Cancel a triggered effect that chooses a Noble character as the only target. Then, draw a card. (Limit once per phase.) ), what cancel the wildling?, the draw card effect only, or the cancel of eddard wich make him draw a card? I suppose the same question goes to similar cards as Longship Iron Victory, she cancels the draw effect or the original effect wich makes a player draw a card?...
