you should improve the mana base if you want it to be competitive, fetches and battlelands will do well.

Penga_is_a_Nugget,

There are currently no battlelands or fetch lands in these colors that are standard. Have any other suggestions on how to improve the mana base?

Oh my bad I thought you were in abzan colors, well there is a new black green man land in OWG also going abzan might help your mana base just by access to more mana flexibility. Also adding white gives you Abzan Ascendancy and some removal. But if you want to stay Golgari definitely get. The green black man land

I think I will stick with Golgari for now, bur I will definitely consider splashing white if I feel like it is to slow for the meta.

Looks good! I like that B/G sacrifice is a thing right now. If the Rogue's Passage is a big piece for getting Nantuko Husk through then I might recommend Sylvan Scrying. Only problem I can see this deck having is exile. Maybe sideboard some enchantment removal like Natural State to take care of nasty Silkwraps. I think there are a few good cards coming from OGW for this build. Good luck!

Thanks for the suggestions FullmetalWes! I will definitely include Natural State in the sideboard and I will have to think over Sylvan Scrying, as Rogue's Passage wins games with this deck.

No problem! Let us know how ya do.
