Looks pretty good. Only things I would say is go 4 Lol Troll and 2 Geist. Double green may be a little bit of a problem in your deck, and the Troll is just too good. Also try to get caverns rather than the guidgates

 {Dreg Mangler} that guy is a must in this deck.    Maybe tragic slips or something.   Those do wonders.

Why is it that good? The scavenger cost is too high...

3/3 haste for 3

What he said.   Plus if it comes down to a lol troll with a mangler in gy and you have the mana, scavenge him for the troll.

I have been very successful with my B/G zombies. I suggest scrapping the geists and definitely putting in dreg manglers. Imagine a turn three 3 3 with haste which also has a good scavenge ability. High yes but good. Definitely run 4 lotleths. Also I would run 2 tragic slips ( amazingg for removal) 2 abrupt decays and 4 golgari charms. Golgari charms are amazingly versatile. Destroy an enchantment, all creatures -1 -1 , or regenerate all creatures? Sickkk. Also I don't run cacklers, but to each their own. Good luck and have fun. In my experience I really have a lot of fun with this deck.
