Zombie World rip-off?

I just sort of threw together the first theme I could pick out, aside from an Archetype.
I have no idea if it's even any good.

Monsters
3x Nightmare Eater
3x Devourer of Fallens
2x Mutated Corpse
3x Necromaniac
2x Great Abomination
2x Greed Jar
2x Shadow Rocklord
2x Hell Master Anubis

Spells
2x Zombieswarm Virus
2x Reverse Destruction
3x Zombrex Spores
2x Corpse Shield
2x Macabre Fusion
1x Mystic Energy Generator
1x Splitting Cut

Traps
1x Maggot Dig
1x Attack Barrier
2x Cursed Moonlight
2x Surprise Vent
2x Re-Do

Extra Deck
3x Death Dealer

Seems to have good swarming potential to me, but could easily fall apart without Zombrex Spores.

Like I said, I have no idea if this is any good at all.

Seems pretty good. I would suggest adding a Corrupted Clown or 2 to search out Devourer of Fallens. Don't worry too much about the type clash - Zombrex Spores should take care of that. You could neg 1 Re-Do, but Idk what else...

Not much targets for Corrupted Clown though other than Devourer. I'll consider it.

At the moment, I'm thinking:
-1 Devourer
-1 Re-Do

+2 Corrupted Clown
+1 Maggot Dig
