dredge 3 and DSC

[Harlequin]

Supose you have a card like Life from the Loam or Darkblast with "Dredge 3" in your yard, and you have a single card in your libary, and that card happens to be Dark Steel Collosus.  I just wanted to verify what happens if you attempt to dredge.
Because both dredge, AND the DSC's re-shuffle ability are BOTH replacement effects, this would allow you to sucessfuly dredge your darkblast after milling the same DSC three times... correct?

Therefore going from:
- darkblast in yard, only one DSC in library
to -> darkblast in hand, only one DSC in libary ... when everything is said and done.

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, you may instead put N cards from the top of your library into your graveyard and return this card from your graveyard to your hand.�

You can't use a Dredge 3 ability if you have only one card in your library, even if it is a DSC. If you had three cards, one being DSC, and it kept getting shuffled to the top, I *believe* that would work and leave your library unchanged. It depends on whether or not the mills are handled like draws ('draw x' = x separate 'draw a card' events), or if all cards are milled simultaneously.

It'd work with Grave-Shell Scarab, but not with DSC

[Harlequin]

Ahh I see. 
Can I get someone to verify how DSC would interact with dredge?
do you:
- Reveal the top 3 cards, and if one (any one happens to be DSC) you then re-shuffle that DSC back
Or
- Reveal 1 card, if DSC re-shuffle, if not, then continue until 3 cards have been revieled.

You dredge all three cards simultaneously.

Just for final clarification, from the Ravnica FAQ:

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.

The best ruling I can find concerning this comes from Millstone.
# Since you are putting more than one card in the graveyard at one time, the affected player can choose the order the 2 cards go in. [Aahz 1997/11/17]

This is the closest situation. All cards go into the graveyard as 1 lump action, unlike a wheel of fortune where each of the 7 cards is an individual draw.

My question however has to do with Darksteel colossus or serra avatar. Say you dredge the imp and move the top 5 cards of your library to your graveyard. What happens if one of those is a darksteel colossus?  Since it has a replacement effect, the game treats it as if the event never happened. The darksteel colossus goes from your library to your library so do you have dredge another card?

The key to this issue is how the ability is defined. Dredge is defined as : Take the top 3 cards of your deck, and put them into the yard simultaneously. It is not like with drawing cards, where any instance of Draw N is automatically replaced by N* Draw 1.

It does not matter where the cards end up--just that you started with the action of "dredge X cards".

Thanks Jacob. For some reason, I was thinking dredge was an activated ability that created the replacement effect. I should have known better since dredge doesn't use the stack and doesn't have a colon in it.

Just a brain fart on my end.
