Good black removal for standard?

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

[LinkCelestrial]

{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.
