Also, I don't think you need both
Doom Blade and
Go For The Throat. I'd have 4 of one or the other, and sideboard the other card if needed.
10 Creatures seems a bit on the low side. You might want to look at
Wight of Precinct Six, or
Nighthowler (both similar to
Consuming Aberration, growing in P/T with each creature/card in your opponents grave yard). But you'll want to watch out for things like
Psychic Spiral, which could result in you suddenly finding yourself with low P/T or
dead creatures. Maybe some counter spells to help
stave off such disasters...
