You might be right, Immortal Servitude could be a good addition, but only in the sideboard. Killing Wave has always been my killing blow, so I don't need anything after that. But when the day comes, the card will be in my sideboard.

Thanks

You're trying to be a Zombie deck and NOT running Geralf's Messenger ?

Get some Garruk Relentless up in here!

There are so many cards to run before Garruk Relentless should even be considered. Messenger and Varolz, the Scar-Striped being the first two I can think of off the top of my head.

Check out my deck Battledriver RDW I think it would compete very well against your deck. I am planning on taking it to my local PTQ I think. One thing I noticed about your list of results is that you face very few control type decks. I didn't see a single one in your match ups. Your local meta must play alot of aggro. I also think your deck could really benefit from Scavenging Ooze , Varolz, the Scar-Striped , and Putrefy If not in the main definitely as sideboards threats.

Garruk Relentless  ^Flip is an awesome card but it doesn't fit in this deck. It's too slow.

Scavenging Ooze could be a good addition as a sideboard, for the other 2, I'm not sure at all...

I have made a lot of testing against control, and it went very well, but making test and playing against a good player is 2 very different thing. I just don't know what to expect. I hope I will play against some at my next FNM.

Thanks for the comments : )

How about Tracker's Instincts and a few Lord of the Undead, shouldn't hurt the mana curve too much and you can cast what you might have to discard with trackers?

I've recently put a zombie deck together if you wanted to check it out, Dead Man's Hand
