This weekend, 32 players converged at Geoff Moes' house to play an invitation only magic tournament. We imbibe (Way more than we should) and play vintage, then we watch the Ohio State/Wisconsin Big 10 Championship (Fuck Ohio State, BTW) and then swim in his pool and party.
Anyway, it was a blast. But the reason I'm writing this is because @sillysam71 (Sam Krohlow) and I have worked together on Doomsday decks several times in the past - He is not very well known because he started playing Vintage shortly before the Midwest Scene died, but trust when I say he is a master at playing Combo decks. I would say Joshua Butker, @Smmenen , Sam and I by far have the most experience with Doomsday in the Format.
Anyway, we designed and played the same 75, with me going 3-2, and him losing in top 4 after going 4-0-2.

1 Bloodstained Mire
1 Flooded Strand

I ended up beating Thing in The Ice RUG Tempo, Kelly Oath, and Jeskai Bomberman, losing to Lands(!) and 2 Card Monte.
In game 1 against lands, I used top, fetched, used top, fetched, and found all my duresses and flusterstorms and lands, and literal no business. Eventually dying to a 20/20. In game 3, I gitaxian probe his hand of all blanks, play necro, necro down to 3 (Which is only 8 cards here) and draw a hand that can kill him, but I don't draw a duress or flusterstorm, so I have to go blind. His 1 unknown card after he draws for turn happens to be Mindbreak Trap.
2 Card Monte was just rough. In game 1 I spin top with fetchlands 3 times to see 9 total new cards, and they're literally all my lands. In game 2, he just demolishes me with Trinisphere + REB, then he grindstones me for value with his two grindstones in play the turn before I can bounce the 3ball and win, and hits both Laboratory Maniac and Tendrils (With Leyline in play). The risk you take playing 2 wincons.
While most choices are pretty obvious, I wanted to talk about some of our choices.
Skeletal Scrying over Treasure Cruise, Merchant Scroll, Time Walk, and Mystical Tutor
Skeletal Scrying gives us another way to use Rituals, and also is instant and non-blue, dodging Pyroblast and giving us a way to refuel the turn before we want to go off. Also, in a pinch it can start your Doomsday Pile for 1B and 1 Life.
Merchant Scroll is a great card, but when you don't play a lot of colorless mana sources it gets pretty hard, and also we don't need gush to start our piles. Time Walk is an obvious cut in my opinion as I never really want to reset my Storm Count. Mystical I wanted, but with the format being Misstep Haven right now, it made sense not to play.
Laboratory Maniac is in the sideboard because Removal is ripe in every deck, and we feel with 4 rituals, we're really more of a storm deck - however, we wanted to bring in the Maniac to beat Graveyard Hate.
Changes I'd make to the maindeck would be:
-1 Flusterstorm
+1 Thoughtseize or Duress
As for the sideboard, it will change every time, but I feel it was pretty okay for the event. I think maybe you want xantid swarms, but I never felt bad against blue decks.
Sorry for the quickness of this - wanted to get the list public but I'm at work. Feel free to ask questions.
