Good black removal for standard?

I wana make a B/U deck but idk what kind of removal i would have

Load & View in Deck Builder (Beta)

Murderous Cut is, IMO, the best right now.

There's Ruinous Path as a contender for number one. Otherwise there's:

Ultimate Price and Reave Soul for reasonable cheap removal.

There's Complete Disregard and Grip of Desolation for some exile.

There's Flesh to Dust and Unholy Hunger for crappy removal.

Then there's Titan's Presence and Scour from Existence for jank.

Seen a lot of languish too, depending on your creatures.
