After using LED in Vintage Ichorid, what I noticed was the best hand that deck draws is Bazaar of Baghdad, Dredgers and LED. The LED puts the Dredgers in position to be Dredged on the first turn, which leads to either a turn one or turn two win 99% of the time.
DA is, in essence, a bad Careful Study on the play. You're best play is to cast either one of them before or after LED, but DA is useless with out LED where Careful Study is effective. What you want is to maximize your Breakthrough + LED, Careful Study + LED or Cephalid Coliseum + LED plays and then run just enough DA in order to spend the remaining UU and Dredge a second time.
What I found was that Dredge was built on a bad premise, we took Manaless Ichorid and kept the original engine with out questioning whether or not the original engine was superior to draw spell + LED, and it turns out that it isn't, because people aren't drawing after the coin flip, and relying on being on the draw to maximize your speed is dubious for a number of very obvious reasons.
I have to admit tho', I have been looking at 4 Breakthrough, 4 Careful Study and 4 Deep Analysis, removing Putrid Imp for Nether Shadow and removing Gemstone Mine for Deep Analysis. The idea is that adding Careful Study A) increases/maintains outlets B) consolidates mana costs into U C) reduces the need for lands D) supports Force of Will in the SB and Putrid Imps function is replaced by EOT discard/dredge and increased threat density from Nether Shadow when it matters the most, game 2 on the draw where the opponent elects to go first in order to drop Tormod's Crypt.
It's 100% experimental, but I think it goes to show you that there are a lot of things we've taken for granted, and Dredge is not set in stone.
4 Golgari Grave Troll
4 Stinkweed Imp
4 Golgari Thug
4 Cabal Therapy
4 Ichorid
4 Nether Shadow
4 Narcomoeba
4 Bridge from Below
2 Dread Return
1 Cephalid Sage
1 Flame Kin Zealot
Note: It's often 4 Dread Return because I hate Cephalid Sage and Flame Kin Zealot and Dread Return is superior in draw, discard, dredge mode.
4 Careful Study
4 Breakthrough
4 Deep Analysis
4 Lion's Eye Diamond
4 Cephalid Coliseum
4 City of Brass
It operates under the assumption that Putrid Imp is both A) too slow and B) worthless in the discard pile compared to Nether Shadow, which feeds Ichorid, recurs itself and is a permanent threat. It focuses on the fundamentals, the LED, Cephalid Coliseum and DA engine on the draw, the LED, Breakthrough or Careful Study and DA engine on the play and is superior in draw, discard and dredge mode thanks to Nether Shadow. You lose some consistency, like 2 lands for Cephalid Coliseum, one land for Breakthrough or Careful Study and one land for Cabal Therapy, but you also gain consistency in Careful Study, LED + DA at 4x and Nether Shadow.
I don't have enough practice with that list, but in theory, it's the farthest you can push the deck in terms of speed and the strongest you can make the deck in terms of draw, discard, dredge (sans Street Wraith).
Edit: I've also tried replacing City of Brass with Lotus Petal for hands of Cephalid Coliseum, Breakthrough and land, where I could Breakthrough on the first turn and then activate Cephalid Coliseum on the second turn with Lotus Petal or draw, discard, drege and then activate Cephalid Coliseum with Lotus Petal once Dredgers were in position, but you lose a lot of other plays as well, Careful Study and Breakthrough, 2xCareful Study, Cabal Therapy protection etc.
Don't get me wrong, I like Putrid Imp, and I love turn one Land, Putrid Imp pass. Dredge and then either Breakthrough, Careful Study or Cephalid Coliseum, but you have to run 12 lands just for Putrid Imp, albeit those 12 lands also support Breakthrough, Careful Study, Cephalid Coliseum, Deep Analysis, Cabal Therapy and the SB to an extent, but any cards that forces you to run lands in Dredge is bad.
I'm sure there is a medium for all of these concepts, but at the moment I don't have the time to come to a conclusion, and other people's opinions may differ on said conclusion. All I know for certain is that 4 Lion's Eye Diamond, 4 Cephalid Coliseum, 4 Breakthrough, 4 Careful Study and 1 DA is the starting point for the best possible Dredge deck, the rest is in 1+ DA, the land ratio and whether or not Putrid Imp and additional lands is worth 4- DA and Nether Shadow.
