Rulings:

• 6/7/2013 Dredge lets you replace any card draw, not just the one during your draw step.
• 6/7/2013 Once you decide to replace a draw using a card’s dredge ability, that card can’t be removed from your graveyard “in response.” (Replacement effects don’t use the stack.)
• 6/7/2013 You can’t use dredge unless you’re going to draw a card and the card with dredge is already in your graveyard.
