Sorry to double post, but here's my current list, with the aggro sideboard option:


Mana (31)
8 Plains
4 Flagstones of Troikar
4 Ancient Tomb
4 City of Traitors
4 Wasteland
4 Mox Diamond
2 Kjeldoran Outpost
1 Scrubland

Control/Lock (17)
4 Chalice of the Void
4 Crucible of Worlds
4 Smokestack
3 Trinisphere
2 Tangle Wire
2 Armageddon
2 Humility

Win Conditions (8)
4 Lingering Souls
2 Timely Reinforcements
2 Elspeth, Knight-Errant

Sideboard (15)
3 Tormod's Crypt
3 Oblivion Ring
3 Honor of the Pure
2 Brimaz, King of Oreskos
2 Timely Reinforcements
2 Tangle Wire

I'm thinking about switching the Oblivion Ring and Humility Slots, with 2 Humility/1 O.Ring in the board and 2 MD Oblivion Ring, both for synergistic effects between Smokestack and Oblivion Ring and for the fact that Ring is more of an all-purpose answer than Humility, which is really only good against tempo, Elves, Goblins, and Show and Tell. Ring is better against tempo because it only costs 3 and you can usually survive a few delver hits before you start binging on their permanents, and can then selectively kill DRS, SFM (or the equipment that SFM finds) or Goyf, which tend to be the creatures of theirs that cause you trouble. Against Elves and Goblins, you really just need to buy time until you can get Chalice @ 1 + Stack, and Ring can keep the worst of their creatures at bey until you lock them out. The sideboard has been pretty effective so far, especially because in physical games you can take the approach of shuffling your board into your deck and then pulling 15 cards out, meaning that if you go to 3 games you can easily give your opponent dead cards in games 2 and 3 by alternating between the approaches. Tangle Wire has been awesome when you're on the prison plan, but the aggro version might be better with 2 Jalum Tome in the SB Wire slots. Brimaz, King of Oreskos means you just win if he gets to stick around for more than a turn.
