Scooping And Into The Dungeon

[Zelc]

After taking a look at Into The Dungeon, I had an idea: a deck based around making infinite mana (Mischevious Quanar + Early Harvest?) and casting an infinite amount of Into The Dungeons (Burning Wish + Mirari + an arbitrarily large number of tables?) to dump the opponent's library into his hand (It even gets around Gaea's Blessing!  Take that, Laquatus!).

Now, that would mean that scooping is a good thing, so obviously your opponent would try to do that too.  Which brings me to my question: who gets to scoop first?  Of course, it's possible that this follows the NAP gets it last rule for infinite loops, but this doesn't really use the stack...

So, does the AP get first chance to scoop?  Can the NAP out-scoop the AP?  Or, would it just be a draw?

This has been discussed in several places before, but I don't think a official answer has ever been generated. Lest you think you need unhunged cards to make this situation, both players have [card]Second Chance[/card] in play, are at ten life, and one plays [card]Shaharazad[/card]. Who gets to scoop and take the extra turn?

My gut tells me that AP/NAP comes into play. When dealing with things that use the stack, NAP get the last word. However, concession doesn't use the stack. For that reason, I think AP theoretically gets the first chance to announce a concession.

If you both conceed, then you'd both lose, ending the game in a draw.

I thought conceding doesn't use the stack and that whoever says it first concedes first.

This was covered once on 'Ask the Judge' on SCG, with the question using top 8 matchups as a reason for both players wanting to concede. I looked through the archives, but couldn't find it, but I have memories of it being the active player's first choice.

If you both conceed, then you'd both lose, ending the game in a draw.

Jacob is correct.
