spiritus ex infernis (EDH / Commander) [Revision 1]

This is a super-fast monoblack spirit deck that uses Iname, Death Aspect to get all spirits to the graveyard, and then turn around and sacrifice Iname for mana to cast a reanimator spell either directly or to tutor for one. Sorcery speed graveyard removal is to slow to deal with this deck, but continual effects cause it to fold quickly, especially if they are artifact or enchantment based graveyard-exile effects.

Most games with this deck will lead to every opponent scooping, especially if you get the combo in play (in other words if you don't have Kuro and Horobi in hand).

The downside - if someone manages to exile all your spirits, you might as well scoop. You cannot win.
