Since there's no clean way to show trades with people not using Deckbox, I'm just documenting using another faux deck list.

Main Deck: Card I got.
Sideboard: Card I gave up.

{Pending approval, as I type this.}

It's a risky trade, and I'm losing about $2 value.  But, it's now looking like I'm going to be committed to the Devoid deck.  I'm considering Inverter main deck as a late game play to get either my control spells or Defiler back, also useful in a pinch when I need a flyer.  Alternately, maybe I sideboard him to bring in against the mill i will likely see in mirror match.  Risk is too much of the stuff I'd want back being exiled instead of hitting the graveyard.
