502.47. Dredge
502.47a Dredge is a static ability that functions only while the card with dredge is in a player's graveyard. "Dredge N" means "As long as you have at least N cards in your library, if you would draw a card, instead you may put N cards from the top of your library into your graveyard and return this card from your graveyard to your hand."
502.47b A player with fewer cards in his or her library than the number required by a dredge ability can't put any of them into his or her graveyard this way.
* Dredge lets you replace any card draw, not just the one during your draw step.
* 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.)
* You can't use dredge unless you're going to draw a card and the card with dredge is already in your graveyard.
donc tu dredge, et tu te défausse
a savoir que le dragage d'une carte remplace la pioche d'une carte, si tu devais piocher deux cartes tu peux en draguer une et piocher la deuxieme
