Hey again, HuntedWumpus. I posted a tournament report in this forum that details my exploits with my B/G Nether Void deck (See:
http://www.themanadrain.com/forums/viewtopic.php?t=6431 )
After looking over your threads, I must admit that I made several changes that adhere more to your deck. For one, I removed the Negators completely - they're not in the deck OR the sideboard, although that could change in the future. I have some work to do on the sideboard, and Negator or Masticores could surely take up a few good spots.
I ran a creature base of 3x Nantuko Shade, 3x Hypnotic Specter, and 2x Withered Wretch. I must say, I thoroughly enjoyed not having Negators to worry about - the Shades were far more durable.
I'm starting to wonder about Blurred Mongoose - he might just be something to seriously consider. I'll perhaps slot 3 of them into my deck in place of Hypnotic Specters and see how they do in the next tournament - maybe you're onto something.
Regarding the overall base though, I think I suggest you drop the total # of creatures to 12, freeing a slot for a swamp. Then switch the Sol Ring for a Wasteland. 4 Mishra's Factory's is pretty much standard, but I would personally drop a Nantuko Shade for a swamp in your build.
Now, here's a sideboard card you CANNOT afford to leave out: Chains of Mephistopheles. Vs. anything with Bazaar of Baghdad, Chains of Mephistopheles is seriously f***ing key. Vs. anything that relies on card-advantage through drawing, Chains is seriously f***ing key. Get 3 copies of that card and stick them in the sideboard, then play them against anyone that uses Keeper, BBS, Dragon, or anything that draws a lot. You'll be very glad of it.
Here's what my deck looks like now.
3x Nantuko Shade
3x Hypnotic Specter
2x Withered Wretch
4x Mishra's Factory
4x Duress
4x Hymn to Tourach
4x Sinkhole
4x Wasteland
1x Strip Mine
1x Necropotence
1x Demonic Tutor
1x Demonic Consultation
1x Yawgmoth's Will
3x Pernicious Deed
3x Nether Void
4x Dark Ritual
1x Black Lotus
1x Mox Jet
1x Mox Emerald
7x Swamp
4x Bayou
3x Polluted Delta
Sideboard:
1x Withered Wretch
2x Tormod's Crypt
3x Choke
3x Chains of Mephistopheles
3x Naturalize
3x Contagion
Speaking off the cuff, I think I'd redo my sideboard like this:
1x Withered Wretch
2x Naturalize
3x Choke
3x Chains of Mephistopheles
3x Contagion
3x Masticore
