Gild vs. Bile Blight

[CommanderUnderSorin]

I am runing black-white midrange. And I'm Trying to get ready for a big tournament(like unaware of the meta)
And I am running 2  {Gild} to remove gods game one and help ramp, if necessary.
But I am unsure to replace with bile blight because my deck is drowing in 4 drops.
Thoughts on main boarding  {Bile Blight} over gild?

Keep bile blight

Throw revoke existence into SB?
