Golgari does whatever a spiderpig does:

CMC
{1]: 4 Death Cultist, 4 Pharika's Chosen
{2}: 4 Satyr Wayfinder, 3 Treasured Find
{3}: 1 Beastmaster Ascension, 4 Necromancer's Assistant, 1 Bloodflow Connoisseur,
{4}: 4 Gravedigger
{5}: 3 Spider Spawning, 3 Rescue from the Underworld, 1 Shadowborn Demon
{6}: Nothing
{7}: 3 Pelakka Wurm, 2 Rune-Scarred Demon
{8}: 1 Griselbrand

Lands:

10 Swamp
8 Forest
4 Golgari Guildgate

Now, this is a fun deck imho.

Rather well-oiled.

It's a combination of spider spawning and rescuing fatties - the critters are chosen as early defenders, mulligan for a starthand with satyrs/necro assistants and the early game you are often under pressure. As soon as you hit mid-game, things should turn around once you resolve the first spiderbatch or fatty. Gravedigger targets are most often the little guys to keep the mill going.

Enjoy.

Version 2 has seen some changes - you don't need 3 wurms or 2 tutor demons, so cut 1 of each - beastmaster ascension has only been a win-more, so that didn't make the cut, Griselbrand just as well, win-more but not really useful beyond that. Gravediggers are amazing, but 4 was 1 too many, as you want the ratio between that and the satyrs and necromancers to be more in the favor of those and not the digger. In to the deck comes 4 Visionarys for early game and 2 reclamation sages for removing that pesky enchantment or whatever that threatens to ruin your fun. Bloodflow stays in, very valuable when you need to fill your yard before a spider spawn. I tried running without the guildgates for a while to speed it up, but I saw a decline in consistency in getting either a green or black mana early and that is more important than a potential speedloss. When digging with Satyr, you can always choose gate or land if they both come up, based on if you need the mana immediately or not.

Enjoy.

[edit]

Addendum: you need to mulligan if you don't have either satyrs and elves or other of the startup cards, else you risk stalling and if your opponent actually has managed to build something that works, you will get run over. If you get them though, it's basicly smooth sailing. Current steam ratio: 40 wins, 8 losses. Of those 8 losses, 2-3 was mana related, one game I mulliganed to 1 card without seeing a land and apologized to opponent and conceeded. The other 5ish losses, 3 of them I didn't get going at all, just playing 1cost creatures and waiting for the inevitable and the last 2 I was completely and utterly destroyed. Even with good draws, and everything was on curve, I got oblitterated.

I know the ratio doesn't mean much, as I run into many new players and at least 25% 80+ card decks. But you can always compare to how your own ratio feels like, and summarize that way.

[edit again]

I took out another wurm, 1 really does the trick. In goes a prime target for Rescue: Ogre Battledriver
Another change - Pharika's Chosen out, Phyrexian Rager in.

Very often, the play is rescue in opponent endstep followed by spider spawning in your mainphase or post attack. Well, with that baby in play, it just gets insane and if they don't have a Fog handy, it's usually GG.
