I'm happy with the list for the most part, but there's room for work. I expected a very diverse meta, with about an even mix of "The big six" (tez, oath, tps, stax, fish, mirror). The points I wanted to hit while building were:
1. Don't mulligan out of game one
2. Don't lose to Wasteland
3. Don't lose to the mirror
Lion's Eye Diamond and Ancestral were attempts to solve problem 1, Ancestral I'm happy with but LED was a failure. I'm still looking for a good answer to this problem before I go around calling myself a dredge player.
I would think Chalice of the Void would be your best bet for the first. Chalice for 0 can at least buy you sometime if you don't have a Bazaar. No other card is going to replace Bazaar, but Chalice can be played on it's own which is better then any spell requiring mana.
I actually kind of thing running my own Strip/Wastes is a decent idea for the last two. Again, they also can give you something to do if it's the last card you have. Obviously, it's great in the mirror. Most fish decks are like three colors with low basic counts and need multiple colors. I don't think there is too much Tarmogoyf either so the clock isn't that fast. Might not be that great since Noble can help them out a lot though. Against Shop decks you can almost hurt them as much as they hurt you, especially if you drop Chalice @ 0.
