Alright guys, I was reading this thread today, and decided to make an account so I can start on this great forum. I started playing Dredge about a month ago, and I'm about 3 cards ($7) short of finishing my list (PM me if you have Modern Masters Cities of Brass!) Anyway, I'd like some feedback on my list, because I don't really think it's the normal list:

Mana:
4x Lion's Eye Diamond
4x Mana Confluence
4x City of Brass
4x Cephalid Coliseum
1x Gemstone Mine

Draw:
4x Careful Study
4x Faithless Looting
4x Breakthrough

Dredgers:
4x Golgari Grave-Troll
4x Stinkweed Imp
3x Golgari Thug

Recursion:
4x Bridge From Below
4x Cabal Therapy
4x Narcomoeba
3x Ichorid

DR Package:
3x Dread Return
1x Flame-Kin Zealot
1x Griselbrand

Sideboard:
1x Gemstone Mine
3x Lotus Petal
1x Chain of Vapor
3x Firestorm
1x Memory's Journey
3x Abrubt Decay
1x Elesh Norn, Grand Cenobite
1x Ashen Rider
1x Iona, Shield of Emeria

I would say it's definitely more on the combo-y side of Dredge, but I really want to hear some suggestions.

EDIT: Only been to 1 local event but I 4-0ed it with a list 1-2 cards away from this.
