Mogg War Marshall isn't needed to trigger Recover, because the only Recover spell in the deck now is Grim Harvest, and the Augurs provide a very potent sac outlet indeed. In fact, the crux of the deck has now shifted to the synergy between the Augurs and Grim Harvest (hence the deck's name). I took out Shred Memory because the spells at the 2-drop level are either essential to the deck (the Augurs) or are unnecessary. Plus, I've found heavy reliance on Transmute to be too slow for competitive Pauper.

Another big change is that I took out the land destruction element, because Augur of Skulls moves the deck in a discard direction, which I feel is the correct direction to go. Land destruction is difficult to maintain, and even if you keep blowing up lands, they can slip some creatures through to cause problems. By recurring a discard stick, you can keep their hand empty, and kill whatever does manage to come down.

Dimir House Guard is left in, however, to fetch either Wrecking Ball or Subterranean Shambler, whichever is more necessary at the time. Of course, the House Guard may also be cast as a 2/3 evasive regenerator, and serves as a solid win condition alongside recursive Emberwilde Augurs.

The removal suite may need tweaking, now that I look at it. Last Gasp was a remnant of the 2-drop tutoring made possible by Shred Memory, and now that it's gone, perhaps something that can kill Baloths, Aurochs, and Ephemerons may be better. (The black seal comes to mind.) Additionally, there could be an increase in dedicated discard (though the black augur does seem pretty potent on his own). This isn't the finished product by any means, but it's a strong start to a deck that should be competitive in the current Standard environment.
