Return up to three target land cards from your graveyard to your hand.
Dredge 3 (If you would draw a card, instead you may put exactly three cards from the top of your library into your graveyard. If you do, return this card from your graveyard to your hand. Otherwise, draw a card.)

Officiele 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.
