Gatherer Card Rulings [Nov 2009]

• 10/1/2007: A permanent that's both a Merfolk and a Faerie is counted only once when determining X.
• 10/1/2007: The value of X is determined when Silvergill Douser's ability resolves. It won't change later, even if the number of Merfolk and/or Faeries you control changes.
