I don't see why Mind Unbound is in the deck if you aren't Running anything to give you an unlimited hand size like a Venser's Journal you'd mill yourself if you faced a deck that could hold you off. What you could do instead of Mind Unbound is maybe switch in Endless Ranks of the Dead you won't have to discard like you would with Zombie Infestation and you'll get more then 1 zombie token per turn. Also I don't think you need 2 Rooftop Storms in the deck considering that you aren't running a single zombie that is below a 5-drop. As well maybe take a look at Havengul Runebinder he may cost 1 more mana to cast but he makes counters for your zombies so they'll get bigger then just +1/+1 and the buff won't dissapear when Havengul does and you'll still get your zombie token. +1 btw!

I'd say yank out Mind Unbound and put in Necrotic Ooze. So many of your creatures have activated abilities I feel like it will give you more utility than drawing cards.

@MarkBGH I never even thought of Necrotic Ooze thanks.

Ghoulcaller's Chant seems pretty bad, because if you return creatures from your graveyard to your hand. It renders Havengul Runebinder Cemetery Reaper pretty useless. So I would cut it.

+1 for flavor.

Here's my zombies: http://tappedout.net/mtg-decks/mono-zombies-1/

I would definitely replace Unbreathing Horde with Geralf's Messenger

I don't want to be rude but...

Most games you don't have a play until turn three; aggro will wreck you.

The rooftop storm combo is silly and overrated.

Before you ask, yes I play a zombie deck. It's currently gone 4/1, 3/1, 3/1, 4/1. Mono green aggro is the only deck I've lost to ... damn swords ...

Do you not see the combo you are sitting on? deck:storm-born

The Grimgrin, Corpse-Born, Gravecrawler, and sometimes Rooftop Storm kill everything combo? Yup I use it. Just thought it was common knowledge.

No. The Grimgrin, Corpse-Born, Gravecrawler, Rooftop Storm, + Diregraf Captain = infinite -1 life.

oh yeah sorry I got it wrong. :)

That's turn 5 game over.

Yeah but you need 4 cards to make it work.

That's why I posted a link to my deck.

Thanks that was cool of you. :)

Why's all your removal just sitting there in the sideboard? You're not going to be able to defeat anything with a decent ramp engine (wolf run). Take the Evil Twins and swap them with the Geth's Verdict in the sideboard. Also, keep at least 2 Mana Leak mainboard. Have Doom Blade and Go for the Throat ready, either in the side or main boards. Then you'll be able to play defensively as well as offensively.
