Forum:Dark deck help?

This is my deck, main plan is to load up the graveyard with dark monsters for TDC, Dark Nephetys, Darknight Parshath, and those lvl 2's for Junk Synchron. The deck isnt finished yet as Im planning on adding another Dark Nephetys and Parshath, add some necro gardnas once I find them, and some malis as milling those would help my deck quite a bit. But I seem to be lacking power and my hand gets empty too fast. Sometime I get dead draws too. Any suggestions?
