I took the golgari deck and edited it a bit. The changes are:
In the description of the deck, I have the edits I have made. I made some more and they are:
Svogthos, the Restless Tomb, Abundant Growth, Dakmor Salvage, Ghoul's Feast, Golgari Grave-Troll, Shambling Shell for Haunted Fengraf, Explore, a Swamp to take out Dakmor Salvage, Champion of Lambholt, and Gravedigger. I chose the Champion of Lambholt because since creatures rotate from grave to hand to battlefield quickly, i decided Golgari Grave-Troll would prove useless. I am trying to find a replacement for Boneyard Wurm, and will most likely have one by the end of the day.
The chief observation I have is that your deck is incredibly inconsistent. I would focus on picking a smaller number of key cards and running more than 1 or 2 of them. So, if you want to run a Dredge strategy, for instance, focus on cards like Golgari Thug that let you self-mill and use your graveyard to your advantage. If you want to run a Scavenge strategy, Slitherhead and its buddies from RTR will be useful. As a rule, though, B/G tends to like getting as much utility out of stuff dying as possible.
That said, your curve is good, and your mana base seems to work fairly well with this particular build.
If you'd like more specific advice on cuts and adds, feel free to ask. Also, as it stands now, you probably want to mark the format of this deck as either "Casual" or "Legacy," as it's out of rotation, and Golgari Grave-Troll is banned in Modern.
This is a kitchen style deck if that helps
If I tell you my extra black and green I think go good with this build, could you tell me what (if any) cards to cut/add?
