I think Strip Mine and Wasteland are superfluous in your deck. You lose focus adding 2 mana denial cards. Maybe those can be Duress #3 and Intuition #3?

4 Force of Will
4 Mana Drain
3 Duress
1 Mind Twist
1 Demonic Tutor
3 Cunning Wish
2 Intuition
1 Merchant Scroll
4 Brainstorm
4 Accumulated Knowledge
2 Deep Analysis
1 Time Walk
1 Yawgmoth's Will
1 Pernicious Deed
1 Gorilla Shaman (Sometimes I wonder about having 2 Shamans)
3 Psychatog

4 Underground Sea
3 Volcanic Island
2 Tropical Island
4 Flooded Strand
1 City of Brass
1 Library of Alexandria
2 Island
1 Mox Sapphire
1 Mox Emerald
1 Mox Jet
1 Mox Ruby
1 Mox Pearl
1 Black Lotus
1 Mana Crypt (Iffy)

Sideboard

3 Null Rod
3 Red Elemental Blast
2 Blue Elemental Blast
3 Rack and Ruin
1 Vampiric Tutor
1 Terminate
1 Berserk
1 Oxidize

I don't think that Salvagers Combo is particularly strong. Dragon has a more efficient combo strategy. However I will concede that your disruptiong looks STRONG!

4 Force of Will
4 Disrupt (!!!)
4 Duress

Disrupt is very good against Draw-7 and decent against control. The weakness of the deck is that it runs slower against an agressive deck in which case the Disrupts and Duresses kind of stink.

Nice thought on Doomsday by the way. :lol: I am however, bemused by the lack of Lion's Eye Diamond in your build.
