Mulch is a cool card. It's like a ghetto version of Life from the Loam.
Simulacrum should be in the deck regardless of what colors you run. It's excellent with Smallpox. If you're going to run green and Smallpox you should consider running Viridian Emissary and Caravan Vigil as well.
The way I see it, there's two things you could do with a BG deck using that engine. The first thing is to make it a more or less typical BG Rock deck and have a lot of 187 creatures and ways of hitting the opponent's permanents. It would be pretty consistent but probably lack the raw power of a blue deck.

This deck is basically all about stopping your opponent from doing what they want by killing their good cards, getting more lands than them, and eating their hand. The deck is based around these simple principles and everything in it is designed to help with that goal. Rock is traditionally a metagame deck, so you can change stuff around depending on what you typically play against in tourneys.
Inkmoth Nexus is not really necessary to the deck, you can cut it for some swamps if you want. It does have some synergy with Phyrexian Crusader post-board though.
Phyrexian Revoker is basically good against the entire metagame. He can stop Splinter Twin by naming Deciever Exarch. He can stop Birthing Pod by naming Birthing Pod. He can even help against aggro decks game 1 by naming Sword of Feast and Famine (although against Aggro you should board him out game 2 for Phyrexian Crusader or Go for the Throat). He's just an amazing card if used correctly and he can hit for two, which is why he's in the maindeck instead of just the sideboard. Oh, and don't play Smallpox if you have nothing but this guy out. Obviously.
Viridian Emissary and Solemn Simulacrum are there for the obvious synergy with Smallpox. The added fact that Emissary is a 2 power creature for 2 is also nice.
Thrun is maindeck here. Problem, blue decks?
Acidic Slime is the only 187 that made it into the final draft of this deck because he's phenomenally good at eating your opponent's equipment/enchantments/lands. If you want you can also run Skinrender, but there's enough creature kill here right now imo.
Massacre Wurm and Grave Titan are your win conditions. Massacre Wurm is going to help a ton against creature decks and Grave Titan makes all your Smallpoxes pretty safe since you can just sack a zombie. Spider Spawning is another win condition here. After several Mulches and Smallpoxes, you'll have a sizeable graveyard with lots of creatures in it. You can take advantage of it by flashing back this late game and getting
a legion of SPIDERS! Definitely board it out it against opponents you think will run mass removal like Black Sun's Dawn or something.
Vengeful Pharaoh was a good idea. The synergy between him and Liliana is very strong. Liliana is going to be mostly used for card advantage with her +1 ability once you get a Pharaoh in the graveyard. Her -2 ability will be used somewhat more sparingly. You'll probably never use her ultimate ability though, partly because it's not that special for an ultimate and partly because they'll try to kill her first (and probably succeed).
Caravan Vigil is a neat trick to do to make your Smallpoxes more potent mid-late game. For BBG, you can get back a land that you sacrificed and have it untapped. Unless of course I'm misinterpreting the word "died", but I'm pretty sure it's just the new version of "put into a graveyard from play" and not just "destroyed through combat damage" or something.
I'm not entirely sure if 4 Mulch is the right number, but it's your only "draw" in the deck so I don't want to run any less.
Dismember is awesome. 'Nuff said.
Crusader goes in against white and red aggro decks. He and Inkmoth Nexus will mostly be trying to race the opponent.
Naturalize and Go for the Throat are good against a lot of things, but will rarely both come in together. The only match where they will is an important match though - Splinter Twin. Against Splinter Twin, you'll board out your Pharaohs, your Vigils, and all your sorcery-speed removal (Acidic Slimes, Massacre Wurm, and a Smallpox) and bring in a 4th Revoker, a 4th Dismember, all your Naturalize, and all your Go for the Throats. The reason why Go for the Throat is used is because it can't be Spellskited. For this reason, it is going to be your very best friend in this matchup. You have a good amount of discard and Splinter Twin probably won't board in Negates against you after seeing that you're heavily creature based. With all this protection, you
should be able to keep them off their gameplan long enough to get there with Thrun.
Everything else in the sideboard is just additional copies of stuff in the maindeck.

What you could
also do with these cards is make a Reanimator type deck with stuff like Postmortem Lunge, Massacre Wurm, Sun Titan, Splinterfright, and Sutured Ghoul. This deck probably wouldn't be very good and it would be VERY weak to Nihil Spellbomb among other things, but it would be a ton of fun:
[collapse="Reanimator Sample Decklist: 61 cards"]
20 Lands
7 Forest
9 Swamp
4 Woodland Cemetery
22 Creatures
3 Spellskite
4 Viridian Emissary
4 Splinterfright
4 Solemn Simulacrum
4 Vengeful Pharaoh
1 Sun Titan
1 Sheoldred, Whispering One
1 Sutured Ghoul
19 Spells
3 Gitaxian Probe
1 Green Sun's Zenith
4 Postmortem Lunge
4 Smallpox
4 Mulch
2 Liliana of the Veil
1 Spider Spawning
15 Sideboard
4 Phyrexian Revoker
1 Spellskite
2 Thrun, the Last
3 Autumn's Veil
3 Mental Misstep
2 Naturalize
This deck is a bit more straightforward. Just get a bunch of cards in your graveyard and do one of three things:
1. Postmortem Lunge for 6 to get Sun Titan, bring back a Spellskite when it comes into play, swing for 6 and bring back Splinterfright, putting yourself in position to win next turn.
2. Postmortem Lunge for 7 to get Sutured Ghoul, exile creatures in the graveyard (besides Spellskite and Splinterfright), swing for a ton of damage.
3. Play Sheoldred and bring back Sun Titan, Pharaohs, etc.
4. Hardcast Splinterfright and beat down with him backed up by Spider Spawning.
The rest of the deck is primarily focused on setting up and protecting the combo.
Spellskite is the primary way you're going to be protecting your Ghoul/Titan/Splinters. He's also a creature that can potentially be put in the graveyard, which is good for Splinterfright (but not Ghoul).
I already talked about Viridian Emissary, Solemn Simulacrum, Vengeful Pharaoh, Smallpox, Liliana, and Spider Spawning in the Rock commentary. In this deck, a 3rd Liliana may be beneficial though.
Gitaxian Probe is really good for combo decks that don't have access to permission or Duress/Thoughtseize. It's a 0 mana cantrip that will tell you if your opponent has a way to stop you or not. If he does, play another Smallpox to get it out of his hand or ramp your mana some more to prepare for a Mana Leak or just dig deeper into your deck to get some more cards. If he doesn't, you can safely go off and you've spent 0 mana to check your opponent. It's really a fantastic card for combo.
Postmortem Lunge is the closest thing anyone will get to Corpse Dance in this format, and because of that I paired it with Corpse Dance's BFF, Sutured Ghoul. The only problem with it is that it costs an almost unreasonable 7 to bring him back but you shouldn't have trouble getting there thanks to Mulch, Simulacrum, and the fact that the game's over when he hits the table. Sun Titan is also a good target for Lunge and it's more reasonably costed. And if there are somehow 20 creatures in your graveyard, you can also Lunge up Splinterfright.
Green Sun's Zenith is only there to be Splinterfright #5+. It's pretty much useless otherwise. I'm considering cutting it for a Spellskite. Or a land.
Revoker can easily be maindeck. The only reason I have him sideboarded is because I doubt anyone's going to run Nihil Spellbomb game 1, which is what will completely destroy your deck.
I totally faked you out and put Thrun in the sideboard this time. Problem, reader?
Autumn's Veil is there to protect your reanimation from counterspells, bounce spells, and removal spells (though Dismember won't do much to any of your targets). Naturalize is to protect your deck from Nihil Spellbomb - they could just activate it in response, but it's better that they do that than in response to you already sinking mana into Sutured Ghoul - and also splash hate for things like Splinter Twin and Birthing Pod. Mental Misstep is a combination of these two.
The deck isn't very good, but it's mostly designed to just be fun.

I also don't think you need to run blue, but if you did then you'd have access to Skaab Ruinator and Lab Maniac. You'd also have access to a bunch of other stuff since Blue is the best color in Standard right now imo.
