BW in standard

Does anyone else think BW is really good in standard right now? I think all it needs is one more card (I really hope it's athreos) to make it a really good deck. It has

{blood baron of vizkopa}
{obzedat ghost council}
{brimaz, king of oreskos }
{desecration demon}
{pack rat}
{heros downfall}
{drown in sorrow}
{bile blight}
{brave the elements}
{orzhov charm}
{elspeth, sun's champion}
{ajani, caller of the pride}
{cartel aristocrat}
{whip of erebos}

There are so many decks to build out of this, I think. White weenie splash black. Mono black splash white. Orzhov midrange. Orzhov control. Some sort of aristocrats deck with {Xathrid necromancer} and {cartel aristocrat} if athreos has some {blood artist} - like ability.

what do you guys think?
