mainboarding duress seems like a mediocre thing to do, I rather have Doom Blade s to deal with the rampant aggro scene, and siding in duress only during control matchups Also Debt To the Deathless can be a 2 of, since it'll be nigh useless in your hand until you untap crypt. increase Obzedat, Ghost Council to 3 or 4 instead, it's a better win-con and it dodges pretty much everything.

Alright, so I took out 2 Duress, moved the other 2 to the sideboard. Replaced with 4 Smites, which combos with Dutiful Thrull to give it a makeshift deathtouch. The 2 Screechers were also replaced with 2 Desecration Demons.

the problem with Smite is that it needs to be blocked. what happens when you have no creatures at turn 3 and they attack for 15 damage? =(

Yes, but the problem with Doom Blade is that it's useless against anything that's black. I think I shouldn't have too many problems getting Priests and Thrulls out there to block and destroy. Flying creatures seem to be my only weakpoint against aggro from playtesting. I don't really like Basilica Screecher though, too iffy and not enough bang for your buck.
