This deck actually performs rather well.  I can't take credit for it, though.  It is the Premium Deck Series: Graveborn.  That is the straight out of the box version.  I got it as a Christmas present when I first started playing Magic.

I like the generators -makes for a stronger mid-game, if you have to last that long. Check out my hidden horror version- more old school, but same basic principles, except relying more on what's in my hand than in opponent's.
