Hey Dave the versions on my deck in this thread are pretty old. Some discussion started and teetered out over here again,
http://www.themanadrain.com/index.php?topic=46708.30. The addition of Urborgs and more mana sources capable of casting Lab Maniac make that problem less of an issue. Also wastelands and force of wills have increased my disruption ability. I have also been running Mayor of Avabruk as another counter to shops game plan as the only reasonable answers are their dismembers/metamorphs with me having Forces to prevent them. Id definitely love to hear your thoughts on how you think my lists could be improved further though.
I personally haven't been a fan of the strictly Depths versions since its reliant on a typically turn-5 2-card combo kill, but I think in a field of less exile effects, like RiP, leyline and Tormod's, it could be built into a pretty threatening force if you can improve on the list. I think step 1 for me would be making the manabase work with Life from the Loam. I definitely like Dakmors+bloodghast over Thug+Ichorid since dakmor is so much better G2/3. I'm also not a huge of a fan of 4 Chancellors over some number of Chalice of the Void, again this is for G2/3 reasons where chalice at 1 can put you way ahead in a lot of blue match ups.
Thanks for the feedback, I'll try Salvage/Bloodghast over Ichorids.
Another version of Dredge I've only seen once was against Vinny Forino. This is a very loose version of what I remember. Anyone have experience with this type of build w/ multi-hate tools of Powder Keg/Ratchet Bomb?
