There's one severely underrated card you currently have little defense against early-on, [mtg_card=Electrickery]. Don't underestimate the "Bonfire for one". ...nor it's speedy Creature cousin, [mtg_card=Izzet Staticaster]. They've already won games for me in Limited against Selsnya/Tokens decks.
Naturally there are a number of cards across Selesnya you can take advantage of (such as [mtg_card=Armada Wurm] and [mtg_card=Selesnya Charm]), but one I'm surprised to see not included is [mtg_card=Champion of Lambholt]. It works beautifully with a tokens strategy, making herself huge and your weenies unblockable (better than Odric does, imho), as well as painting herself a bigger target for removal than your army of tokens, adding a little extra layer of protection and forcing your opponent to make some decisions with [mtg_card=Oblivion Ring]s and [mtg_card=Detention Sphere]s. Also note that a number of your creatures and tokens are Soldiers, making [mtg_card=Captain of the Watch] that much more valuable (especially combined with Lambholt), as a later-game bomb. Might I also suggest, for your consideration, pumping your tokens further with [mtg_card=Phantom General]... basically another [mtg_card=Intangible Virtue] with a body. Another card which I think you could consider for a sideboard is [mtg_card=Gutter Grime], it's expensive, but basically gives you back all of your non-tokens when they die, as bigger tokens that you can Populate or pump. (Obligatory mention of my new favorite and completely underrated card: [mtg_card=Pack Rat]. Gotta love a better, cheaper [mtg_card=Plague Rats] that makes more Plague Rats...)
In fact, if you feel like splashing toward Bant (WUG is Bant, right? I don't remember... whatever) instead of BWG, you could make decent use of [mtg_card=Drogskol Captain] to protect your little fliers (and the General, if you should decide to use him), and/or the ever-popular (and ridiculously efficient) [mtg_card=Geist of Saint Traft]... (who works magnificently with the Populate mechanic, should you change your mind on that). This would also give you access to [mtg_card=Mizzium Skin] for your sideboard, to block spot removal and [mtg_card=Detention Sphere], as well as effectively neutralize the threats from the "trickety", Staticaster, and low-mana [mtg_card=Bonfire of the Damned] with a quick defense boost. These might fit a Spirits theme deck quite well, come to think of it...
...actually, don't do that. I'm doing that. heh.

I've been trying to work out a Golgari graveyard deck with cards like [mtg_card=Splinterfright] and [mtg_card=Grisly Salvage] filling the graveyard with as many creatures and scavenge cards as possible. Unfortunately the scavenge mechanic is just far too slow for what this deck is trying to be, and I usually can't pay the cost for any of them until at least turn 5. At which point there'd be a lot more I'd want for five mana than 3 +1/+1 counters. Not to mention that the deck is very vulnerable to removal. Since then I've been kind of trying to turn the deck into a bit more of a control deck, using creatures like [mtg_card=Ulvenwald Tracker], combined with deathtouch and other shenanigans. Although my hopes are slightly diminished and I might move on to a different deck.
Funny you should mention that. I'm working on a deck right now that combines Ulvenwald Tracker with the lovely [mtg_card=Predator Ooze]/[mtg_card=Nightshade Peddler] combo. It works quite well as a little counter engine for the Oozes and [mtg_card=Lumberknot], especially if you can Miracle a [mtg_card=Revenge of the Hunted] on it for even more Deathtouch shenannigans. If you splash Red, it also gives you some quick attackers in [mtg_card=Flinthoof Boar]. Throw in the absolutely wonderful [mtg_card=Corpsejack Menace], [mtg_card=Lotleth Troll] (THE ace card for any Golgari deck), and [mtg_card=Rancor] alongside [mtg_card=Ring of Xathrid], and [mtg_card=Ring of Kalonia], and you've got quite a solid counter-producing deck on offense and defense. After that, any Scavenge cards, maybe [mtg_card=Mikaeus, the Unhallowed], a green Miracle or two (especially [mtg_card=Blessings of Nature]), and/or [mtg_card=Jarad, Golgari Lich Lord], for some icing on the cake. Naturally, you'll want a healthy dose of [mtg_card=Golgari Charm]s to shut down weenie/token decks, and block mass removals, and probably some Zombie tricks with [mtg_card=Geralf's Messenger]s and [mtg_card=Gravecrawler]s.
Against aggro decks, you could use cards like [mtg_card=Desecration Demon] to slow them down (and bring low-creature decks to a standstill), and against ramp or elves, (if you can survive long enough or pop Liliana's ulti) [mtg_card=Necropolis Regent] or [mtg_card=Craterhoof Behemoth] can end games. Maybe, just maybe, a Golgari deck is the home for [mtg_card=Shimian Specter] I've been looking for...
If you're looking to take more advantage of Scavenge, might I suggest the fairly efficient [mtg_card=Sluiceway Scorpion]s and [mtg_card=Slitherhead]s to discard with the "lol Troll", combine with Corpsejack, and/or just get a body in the way... (in which case, I'd also suggest [mtg_card=Yeva, Nature's Herald] for the lols... and more Deathtouch shenannigans)
