This deck is a thoroughly-modified version of the Torment Preconstructed deck: Grave Danger.  Your aim is to hit fast and hard, and don't ever balk at discarding or milling your own cards.  Organ Grinder, Aquamoeba, and the Atogs are your primary offense.  Discard to keep the Aquamoebas hitting hard, and the Imps airborne and exile your graveyard to keep the zombies alive or the atogs strong.  Use Ghastly Demise and Chainer's edict to open up an attack route, then play False Memories when your opponent has no blockers and give your 'togs a nasty power boost.  Phyrexian Arena and Graveborn Muse should be used judiciously - extra card-draw power means extra discard power and extra grave power, but at a price.
