I'm kind of thinking of taking out the Infamies for Geralf's Messenger. I dunno yet, probably a lot of other stuff that could use fixing, thanks for all advice/criticism.

This deck looks pretty good already, but I'd take out Knight of Infamy .  Odds are you'll be attacking en masse most of the time, which means exalted is next to useless.  And pro white is very situational.  Dreadbore feels like a better option to me, or you could try Brimstone Volley .  Triggering the morbid effect should be no problem with this deck.

-3 Flailer
+1 Hellkite
+1 Hellrider
+1 Guildgate

-4 Shred-Freak
+1 Aristocrat
+1 Knight
+2 Guildgate

-4 Cackler
-4 Ghoul

-4 Noble
+4 Gravecrawler

-2 Mountain
+2 Swamp


You list looks a little mana greedy, hench the Guildgates.  And with the addition of another Hellkite more land is needed (and 22 was too low any way).  Ghoul and Gravecrawler are superior 1 drops to Noble and Cackler.  Ghoul is a Cackler that can block after it's second turn if you have to, and Gravecrawler can crawll out of the Grave.

Messenger would be an ideal turn 3 play (and it further supports Gravecrawler).  And in that event (after making the changes I suggested) I'd be inclined to go:

-1 Hellrider
-1 Knight
-1 Hellkite
-1 Guildgate
+4 Messenger

Other wise:

-3 Flailer
-2 Shred-Freak
+4 Messenger
+1 Knight

Pro-White is pretty relevent, at least from what I've seen.

To the OP: Usually a distinction is made between B/R Zombies and Rakdos (B/R) Aggro. The package suggested by Anabuss of 4x Diregraf Ghoul , 4x Gravecrawler , 4x Geralf's Messenger probably puts this squarely in B/R Zombies territory. Whether this matters I guess depends on your preferences: Do you want to have the most competitive deck that uses the colors black and red or do you want to play a (non-zombie) Rakdos Aggro deck? They do play differently.

[And no, I'm not trying to suggest that B/R Zombies is better than Rakdos Aggro or vice versa.]
